Summary of three cases of energy saving and consumption reduction

Nowadays, "energy consumption" is regarded as an important index to evaluate the comprehensive competitiveness of an enterprise, which confirms a simple and profound truth. Energy consumption index is increasingly becoming an important driving force for the sustainable development of a country and enterprises. Since Ningbo Zhongmao Hangzhou Bay Thermal Power Co., Ltd. was put into production in 20xx, the leaders of the company attached great importance to energy saving and cleaner production, and set up a leading group for energy saving management and cleaner production with the general manager as the leader. With the strong support of company leaders, all employees actively participated. The company starts with technical energy saving and energy saving management, establishes Scientific Outlook on Development, conducts comprehensive investigation, analysis and research on the production status, and determines the key points of energy saving transformation projects. After technical transformation, the reliability and safety of equipment operation are greatly improved, and the energy saving effect is remarkable. In July, 20xx, our company was listed as a pilot unit of energy saving and cleaner production audit in Ningbo by Ningbo Economic Commission and Ningbo Environmental Protection Bureau, and passed the cleaner production audit and acceptance.

First, improve the management network, constantly improve the system, and ensure energy conservation and consumption reduction from the organization.

In order to strengthen the scientific management of energy conservation and promote the in-depth and sustainable development of energy conservation work, a leading group for energy conservation management and cleaner production, headed by the general manager, was established. An energy-saving network, in which the deputy general manager of production is responsible and department directors, relevant technicians, squad leaders or team technicians participate, has been established, and an energy-saving task force has been set up to implement policies, regulations and various energy-saving technical supervision rules and regulations. Further improve the energy-saving technical supervision standards and the incentive system for energy-saving technical measures, so that energy-saving technical supervision can be based on laws and energy-saving management can be further standardized. At the same time, around the overall goal of the company, an energy-saving work plan was formulated at the beginning of the year, which was broken down month by month. Carry out energy-saving network activities every month and analyze the main economic indicators and small economic indicators. While summing up last month's work, the problems existing in production and economic indicators were organized, coordinated, decomposed and implemented, which further improved the overall energy-saving awareness of enterprises.

Second, mass energy-saving work has been carried out in depth, and energy-saving awareness has been further enhanced.

Energy-saving work involves a wide range, involving every corner of the company and everyone. On the one hand, the company conducts external training, invites cleaner production consultants to give training to production backbones and various management personnel, and comprehensively learns the knowledge of energy-saving production and cleaner production, and has a heated discussion. On the other hand, fully mobilize employees, rely on the wisdom and strength of employees, distribute learning manuals such as energy-saving production and cleaner production-oriented catalogues to employees, and organize team learning. At the same time, the computer platform was used to exchange learning experience, and a large-scale report on energy saving and cleaner production was also made. In addition, a special question-and-answer session on knowledge of energy-saving and cleaner production and rationalization suggestions was arranged, and publicity slogans on energy-saving and cleaner production were hung in eye-catching positions of each team. Through the activities, the company formed a good energy-saving production atmosphere, improved the ideology of energy-saving and cleaner production of all employees, made the production backbone and important post personnel have a clear understanding of energy-saving and cleaner production, and created favorable conditions for carrying out energy-saving and cleaner production. The company actively mobilized all employees to carry out rationalization proposal activities and "three small" activities with the theme of saving energy, reducing pollution and increasing efficiency. In carrying out rationalization proposals, we not only focus on large-scale energy-saving projects, but also spare no effort to turn small projects into small ones and save them bit by bit. According to their own work experience, the workers summed up many methods of saving energy, reducing consumption, reducing pollution and increasing efficiency. Through the analysis of the company's production technology and the process flow of each section post, this paper puts forward more in-depth energy-saving and cleaner production measures, which effectively promotes the in-depth development of energy-saving work.

Third, rely on science and technology to highlight key points, grasp key points, seek truth from facts, and reduce energy consumption.

Energy consumption will cause environmental pollution, and energy conservation will be the most effective means to slow down and control pollution. We rely on science and technology to save, rely on science and technology to create benefits, persist in saving energy and reducing consumption, seek survival and promote development; From the aspects of standardized management and equipment transformation, to improve the safety, reliability and operation economy of equipment, we should focus on the big picture, start with the small things, and start from me, bit by bit. In the process control of energy-saving and cleaner production, advanced energy-saving technologies and equipment mainly include:

1, using frequency control technology, such as: induced draft fan, secondary machine, coal conveying system motor using frequency control, hydraulic coupling speed control. After the induced draft fan adopts frequency conversion speed regulation, it realizes soft start and avoids the damage of impact torque to the motor when the high-power motor is started. At the same time, the motor speed can be smoothly adjusted according to the working conditions of the boiler, the air volume can be controlled, the throttling loss can be reduced, the power consumption can be saved, and the thermal efficiency of the boiler can be improved.

2. Adopt softening treatment of circulating water and online cleaning, sterilization and scale prevention of large circulating water system, dredge pipelines, improve heat exchange efficiency of condenser, heat dissipation efficiency of cooling tower and vacuum of unit. After treatment, the vacuum degree is increased by 4kpa, and the coal consumption of power generation is reduced by about 10g/kWh.

3. Transform the flow passage of the steam turbine, clean and adjust the dynamic and static clearance, improve the thermal efficiency of the steam turbine, increase the output of the unit and reduce the coal consumption.

4. The circulating fluidized bed boiler with high efficiency, energy saving and environmental protection is adopted, and flue gas desulfurization technology is adopted inside and outside the boiler; At the same time, strengthen operation regulation, actively carry out small index competition activities, improve boiler combustion conditions and steam turbine operation parameters, and make boilers and boilers run more economically. The coal consumption and auxiliary power consumption are reduced. The thermal efficiency of the boiler is improved, and the emission of cinder and dust is reduced.

5. Use steam turbine feed water pump instead of electric feed water pump to improve the utilization efficiency of self-contained steam and reduce the auxiliary power consumption rate.

6. Adopt new thermal insulation materials such as rare earth with good thermal insulation performance to insulate the boiler and main steam pipeline;

7, boilers, steam turbines, etc. DCS automatic control technology is adopted, and comprehensive relay protection, automatic switching and automatic control technology are adopted for electricity.

8. Replace extraction condensing turbine with back pressure turbine to reduce condensing loss and coal consumption for power generation.

9. Reduce the loss of steam and water, such as restoring qualified water quality after leakage detection of condenser pressure water, regulating boiler regular blowdown, controlling the opening of continuous blowdown, maintaining continuous blowdown water level operation and other measures to reduce the loss of steam and water. At the same time, strengthen equipment management, try to eliminate internal and external leakage of thermal system, and strive for no leakage.

10, actively carry out total quality management activities and improve the original equipment to achieve the purpose of energy saving; For example: design and install the steam seal condensate (desalted water) recovery device by yourself; Improvement of chemical water treatment process: automatic drainage reform of high-pressure heater: operation of oil purification device and oil filter regeneration equipment, etc. We * * * implemented 4 1 free/low-cost schemes for energy-saving and cleaner production and equipment production technologies, 1 1 high-cost schemes. After the implementation of the scheme, the emissions of energy, raw and auxiliary materials and wastes are greatly reduced, and the emissions of sulfur dioxide can be reduced by 26, the emissions of soot can be reduced by 32, the consumption of standard coal for power generation can be reduced by 13, and the consumption of auxiliary power can be reduced by 19? 5. The total thermal efficiency increased by 24? The energy consumption per 10,000 yuan output value decreased by 27%, which achieved good environmental and economic benefits for the company. Energy saving is a long-term strategic policy of national economic development, an important index to evaluate the comprehensive competitiveness of enterprises, and an eternal theme. There is a long way to go to save energy and reduce consumption. We will, as always, do a good job in energy conservation and consumption reduction, and formulate sustainable energy conservation and cleaner production plans, so that energy conservation and cleaner production can be carried out in an organized and planned manner throughout the company.

In the past 2xx years, I will stick to the goal of building a conservation-oriented institution and do a good job in energy conservation and consumption reduction. The energy-saving and consumption-reducing work this year is summarized as follows:

First, leaders attach importance to it, improve institutions and raise awareness of energy conservation.

Effectively strengthen the management and leadership of energy saving and consumption reduction. I will set up a leading group for energy conservation and consumption reduction according to the requirements of my superiors, with the chairman as the leader and the vice chairman as the deputy leader, and set up an office to take charge of this work. The office is specifically responsible for energy-saving work, which is included in the important agenda of the unit and planned and deployed at the regular meeting of the chairman's office. Conscientiously do a good job in energy-saving publicity and consumption reduction education in this unit. I will pay attention to ideological education, focus on the theme of "energy saving, consumption reduction and scientific development", pay attention to science and rationality, improve energy-saving measures, establish the concept of circular economy, carry out energy-saving publicity and education in combination with the actual situation in the office, save a liter of oil for drivers, and all cadres carry out activities to save a liter of electricity, a drop of water and a piece of paper, so that the traditional virtues of saving and diligence are deeply rooted in people's hearts, saving glory and opposing waste. In a conspicuous position in the office, energy-saving propaganda slogans are hung, and posters are posted in the office building. All cadres have improved their awareness of energy conservation and emission reduction, and gradually formed conscious actions in energy conservation and emission reduction.

Second, strengthen energy conservation supervision and attach importance to energy conservation management.

In recent years, I will measure the consumption of water, electricity and oil separately according to the requirements of energy saving and consumption reduction of public institutions, and submit the energy consumption to the county government office on time every quarter and year. Establish an energy-saving statistical system for monthly classified statistical ledgers and quarterly statistical reports.

In order to maintain the good working order of the organization and ensure the smooth daily work of the organization, the daily management system of the organization formulated by our association clearly stipulates the requirements of energy saving and consumption reduction: before leaving work, we should carefully check whether the air conditioners, computers (monitors, printers), water dispensers, shredders, lighting lamps, electric fans and other electrical equipment are turned off, and urge and improve the staff's awareness of energy saving and consumption reduction. At the same time, the fuel for official vehicles is calculated and measured according to the indicators, and the vehicles are strictly checked to reduce fuel consumption. The power-saving and water-saving management of offices, buildings and halls has also implemented the responsibility system for personnel in units (rooms) during working hours, and the patrol management system for department leaders and personnel on duty after work hours, thus putting an end to the phenomenon of running water, ever-burning lamps and not turning off the phone.

Three, strengthen energy-saving measures, and strive to achieve the goal of energy conservation and emission reduction.

(A) the implementation of e-government, reduce administrative costs.

Further improve the construction of office network and vigorously promote government informatization. Make full use of the network to hold cultural meetings, reduce the number of official documents, reduce the number and scale of meetings, and pay attention to the actual effect of meetings; Reengineering and integrating workflow to improve administrative efficiency; Effectively strengthen the management of water, electricity, office, conference, vehicles and other funds, effectively control expenditures and reduce operating costs.

(two) energy-saving transformation, reduce water and electricity consumption.

Do a good job in energy-saving transformation of lighting system and use energy-saving devices or equipment. Actively promote efficient energy-saving lamps. This year, the authorities invested 8 yuan to replace all fluorescent lamps in the office with energy-saving lamps, which effectively controlled my electricity consumption.

(3) Strengthen bus management and reduce vehicle consumption.

Strengthen the management of official vehicles, strictly manage the fuel quota, and prohibit the private use of buses and private cars; Strict management of vehicle fuel consumption and maintenance costs, the implementation of the "one car, one card" refueling system, vehicle fuel consumption and maintenance costs continue to decrease.

(d) Reduce official expenses and pay attention to energy conservation in new projects.

Standardize the system of equipment, procurement and requisition of office supplies, implement the management of consumables by special personnel, reduce the use of disposable supplies, implement the quota management of travel expenses and transportation expenses, make up for the overruns and keep the savings; Advocate short calls, reduce personal calls, and stop chatting in the office.

This year, the expenditure on electricity, oil and water in government agencies and institutions decreased by 2. 1%, and the expenditure on official reception and meetings decreased by 4.8% compared with last year.

Four. Work plan for energy conservation and emission reduction in 2xx years

In order to further improve energy saving and consumption reduction, I will focus on the following three aspects.

First, further deepen publicity and education to promote energy conservation and consumption reduction. Strengthen the publicity activities of laws and regulations on energy saving and consumption reduction, and advocate that office air conditioners should be turned on one hour late for work and turned off one hour before work; We advocate turning off computers, televisions, drinking fountains and other electrical appliances in time after work to create a good atmosphere of "everyone talks about saving, everything talks about saving, and always talks about saving".

The second is to further strengthen management and promote energy conservation and emission reduction. Establish and improve the energy-saving and consumption-reducing management system with clear objectives, clear responsibilities, implementation of responsibilities and strict supervision. Gradually phase out office equipment with high power consumption, save office expenses, advocate saving paper, electricity and office supplies, and reduce the use of disposable office supplies. Every staff member can consciously save paper and water and electricity. Further promote and encourage active energy conservation.

Third, the plenary session advocates a healthy, civilized, thrifty and moderate consumption concept, guides consumption patterns with a conservation-oriented consumption concept, and gradually forms a conservation-oriented consumption model suitable for the actual situation.

During the "Eleventh Five-Year Plan" period, in order to fully implement Scientific Outlook on Development, implement the "1348" strategy and accelerate the construction of a resource-saving and environment-friendly society, under the correct leadership of the county party committee and the county government, and under the serious guidance of relevant departments at the county level, our town focused on energy conservation and consumption reduction, accelerated the effective utilization of resources, promoted clean production, intensified the rectification of energy conservation and emission reduction, and solidly promoted the development of energy conservation and emission reduction, which was effectively realized. The work of energy conservation and emission reduction in our town during the 11th Five-Year Plan is summarized as follows:

First, strengthen leadership and improve the management system of energy conservation and emission reduction.

In order to effectively strengthen the management and guidance of energy conservation and emission reduction, our town set up a leading group for energy conservation and emission reduction in time, with the mayor as the leader and the deputy mayor in charge as the deputy leader, and the main leaders of agricultural comprehensive stations, water conservancy and soil conservation stations, forestry stations, 16 enterprises and 18 administrative villages as members, and set up an office, established corresponding working systems, and defined the energy conservation authorities and related departments in energy conservation management. During the Eleventh Five-Year Plan period, the leading group held regular meetings to study major issues. A series of measures and systems conducive to promoting energy conservation in our town, such as the Comprehensive Work Plan for Energy Conservation and Emission Reduction in Dongkeng Town, were reviewed and approved, which ensured the smooth development of energy conservation and emission reduction in our town.

Two, a clear responsibility, the establishment of energy-saving target responsibility assessment system

Give full play to the leading role of the government and take establishing and perfecting the responsibility system and accountability system for energy conservation as the primary task of current energy conservation work. According to the Opinions on Energy Saving and Emission Reduction in Jingning County during the Eleventh Five-Year Plan and the responsibilities, objectives and tasks of the Eleventh Five-Year Plan energy-saving target responsibility letter signed by the town government and the county government, combined with the reality of our town, the Eleventh Five-Year Plan energy-saving target responsibility letter was formulated, and the energy-saving target was decomposed into energy-using enterprises and key energy-using units step by step, and the responsibility letter was signed with 16 enterprises and 18 administrative villages in the town respectively.

Third, introduce technology, eliminate backward production capacity and optimize energy structure.

During the "Eleventh Five-Year Plan" period, in order to achieve the goal of reducing energy consumption by 20% per 10,000 yuan of GDP, our town intensified the adjustment of industrial structure and promoted energy conservation in key areas. In the specific work of energy conservation and emission reduction, it is emphasized to make use of the opportunity of technological transformation, optimize the industrial structure, eliminate backward production capacity with high energy consumption, and make a major breakthrough in energy conservation and emission reduction. Taking Jingning Zhengyi Stainless Steel Pipe Co., Ltd. as an example, a 20-meter intelligent bottom roller furnace was established during the Eleventh Five-Year Plan period, which can reduce the standard coal by more than 350 tons per year on the basis of the original coal consumption. Annealing furnace equipment is imported from energy-intensive enterprises. Annealing furnace is a new type of heat exchange equipment, and it is an energy-saving periodic furnace with super energy-saving structure and fiber structure, saving 60% electricity. In rural areas, biogas construction has been actively promoted. At present, more than 400 biogas digesters have been built in Dongkeng Town. If 6-8 bottles of liquefied steam are produced every year, 2400-3200 bottles of liquefied steam can be reduced every year.

Fourth, at the same time, take measures to increase publicity and enhance energy-saving awareness.

During the Eleventh Five-Year Plan period, our town has carried out publicity and training on energy conservation and emission reduction for many times in the form of symposiums and competitions, which has aroused the enthusiasm of all parties, raised the awareness of energy conservation and emission reduction in enterprises, institutions and administrative villages, and achieved good results, providing an ideological basis for the specific implementation of energy conservation and emission reduction. At the same time, actively carry out energy conservation and emission reduction publicity activities. In the "Energy Conservation Publicity Week" and "Energy Conservation and Emission Reduction Publicity Month" activities, all levels and departments attached great importance to it, and publicized the knowledge of energy conservation and emission reduction by hanging huge slogans, which enhanced the awareness of energy conservation and emission reduction of the whole society.

Problems with verbs (abbreviation of verb)

1. Some enterprises need to raise awareness of the importance of energy conservation and emission reduction. Individual units don't understand the importance of energy conservation and emission reduction, enterprises can't correctly understand the relationship between energy conservation and emission reduction and economic development, and take energy conservation and emission reduction as a soft indicator, and the publicity is not enough. Some enterprises have extensive management methods, indifferent awareness of energy conservation and emission reduction, imperfect systems, and energy conservation and emission reduction have not yet become the conscious action of the whole society.

2, energy conservation and emission reduction work has not yet formed a joint force. The responsibility of individual enterprises for energy conservation and emission reduction is not implemented, which is a mere formality and has a negative impact on energy conservation and emission reduction; The energy-saving and emission-reduction work of individual enterprises is under the pressure of increasing production capacity and economic development, and is restricted by conditions such as capital and technology, and lacks effective energy-saving and emission-reduction measures.

The intransitive verb "Twelfth Five-Year Plan for Energy Saving and Emission Reduction"

The Twelfth Five-Year Plan is a crucial period for energy conservation and emission reduction. In order to further improve energy conservation and emission reduction, our town will focus on the following three aspects.

1, raise awareness. During the Eleventh Five-Year Plan period, people's governments and supervisory organs at all levels such as the CPC Central Committee and the State Council paid attention to and deployed energy conservation and emission reduction. Villages, units and departments should conscientiously study and understand the spirit of these meetings and documents, raise awareness, earnestly enhance their sense of political responsibility, incorporate the task of energy conservation and emission reduction into the overall deployment of party style and clean government building and anti-corruption work, especially law enforcement and supervision work, and make specific arrangements in time. It is necessary to actively play its functional role, strengthen supervision and inspection, and cooperate with and urge relevant departments to make great efforts to do a good job in energy conservation and emission reduction. Energy conservation and emission reduction should be placed in a more prominent position, and the related work of deployment should be coordinated with the overall requirements of energy conservation and emission reduction.

2. Strengthen supervision. The supervision of all units in villages should be carried out under the leadership of the town leading group for energy conservation and emission reduction, with the focus on rectifying illegal sewage discharge by enterprises, protecting people's health and environmental protection, shutting down and eliminating backward production capacity, strengthening supervision and inspection, ensuring the smooth implementation of government decrees, and promoting the implementation of national industrial policies, environmental protection laws and regulations and the realization of energy conservation and emission reduction targets. To carry out supervision and inspection of water environment comprehensive improvement projects in key river basins, it is mainly to supervise and inspect the water sources in drinking water source protection areas within their jurisdiction, and urge relevant departments to promptly rectify the pollution and hidden dangers that threaten the safety of drinking water sources. By strengthening the supervision and inspection of energy conservation and emission reduction, we will ensure the smooth completion of the task of reducing the total discharge of major pollutants in our town during the Twelfth Five-Year Plan period.

3. Establish and improve the system. The supervision work should closely focus on the realization of energy-saving targets and pollutant emission reduction targets in Jingning County during the Twelfth Five-Year Plan, urge villages and relevant departments to establish and improve energy-saving emission reduction systems, monitoring systems and assessment systems that meet the characteristics of our town, and track and check the implementation of the three systems. Cooperate with relevant departments to urge village departments to conscientiously implement the leadership responsibility system for energy conservation and environmental protection and the target management responsibility system, and promote the establishment of a long-term mechanism for energy conservation and emission reduction through law enforcement supervision. Strengthen daily supervision to make energy conservation and emission reduction work "persistent and persistent". In the construction of the three systems, if the organization and leadership are ineffective, the work is not in place, and the fraud is made, it should be corrected and the responsibility of the relevant responsible personnel should be investigated. At the same time, attention should be paid to strengthening coordination and cooperation among departments, and through continuous improvement of joint inspection, case handling and case transfer mechanisms, a working pattern of unified leadership by the government, joint action by departments and extensive public participation in solving energy conservation and emission reduction problems will be formed.

During the "Eleventh Five-Year Plan" period, our town earnestly implemented the national and Jingning county energy saving and emission reduction policies, and achieved certain results in controlling high energy consumption and high pollution. However, due to the huge pressure of increasing production capacity and economic development, the enterprises in our town, such as steel pipes and power stations, are still facing a very severe situation to fully realize the goal of energy conservation and emission reduction. In particular, individual enterprises are not aware of environmental protection, and the phenomenon of stealing emissions occurs from time to time. Therefore, in the Twelfth Five-Year Plan, we should further intensify energy conservation and emission reduction, make great efforts to solve environmental pollution problems, ensure the full realization of energy conservation and emission reduction targets, safeguard people's environmental rights and interests, and make contributions to the sustained and stable development of Dongkeng economy.
