Significance of straw power generation

Straw power generation is the concrete embodiment of the policy of benefiting the people of the party and the country.

China's vast rural areas, especially the plain areas, mainly rely on grain production, and a large number of straws will be produced every season. In the past, cooking in rural areas relied entirely on straw, cooking pots and smoky fires, and farmers' kitchens were all smoky and black; With the gradual improvement of living standards in rural areas, farmers no longer rely entirely on straw for cooking, so a large number of rural straws are abandoned. In order to save trouble, farmers simply harvest grain and burn straw with fire on the spot. In this way, in the farmland along expressway or near the airport, burning straw often leads to traffic accidents or flight accidents, resulting in huge personal and property losses. So the local government issued a policy, not burning straw, burning an acre of fines 1 ten thousand. But this is not a long-term solution after all. The key is to find a way out for the straw.

Since 2005, the state has successively promulgated a series of policies, such as the Renewable Resources Law of People's Republic of China (PRC), the Supervision Measures for the Full Purchase of Renewable Energy by Power Grid Enterprises, and the Trial Measures for the Management of Power Generation Price and Cost Sharing of Renewable Energy, so as to vigorously promote the development and utilization of renewable energy. Well, with the straw power generation project, farmers' straw will no longer have no way out. Moreover, the straw originally abandoned by farmers can become a reliable economic income. In the 30 years after the founding of the People's Republic of China, our national policy was that industry should feed agriculture, and our farmers made great contributions to the development of industry. After 1980, China engaged in economic construction and its industry developed rapidly. 2 1 century China's industrial development has greatly exceeded the development of agriculture, and farmers' income from going out to work has far exceeded the income from farming. Some people have calculated that the net income of one acre of land for growing grain for one year is not the income of going out to work for one month. The state proposes that industry should feed back agriculture. And introduced a series of policies: agricultural tax relief, grain subsidies, agricultural machinery purchase subsidies. Let grain farmers really get benefits. The farmers are really grateful to the leaders of the party and the country, and even some farmers have invested themselves to cast the "Fuding" as an eternal memorial. It can be seen that the policies of the party and the state have won the hearts of the people. People gradually realize that straw power generation projects should also be viewed from the perspective of "industry feeding back agriculture", which is also a reflection of the policy of benefiting farmers by the party and the state.

Straw power generation is a powerful measure to save mineral resources.

The improvement of people's living standards will inevitably aggravate the massive consumption of mineral resources. The sharp rise in international oil prices is a good example. In just three years, in 2004, it rose from more than 40 US dollars/barrel to 90 US dollars/barrel, once breaking through the threshold of 100 US dollars/barrel. Don't think that China is vast in territory and abundant in natural resources, and the underground oil and coal are inexhaustible. China has become the third largest oil importer. China, however, is still self-sufficient in coal and seems to have no worries. However, we should not take it lightly. For thermal power generation alone, in 2007, the newly added installed capacity reached 8 1.58 million kilowatts. The total installed capacity of thermal power in China is 565.6 million kilowatts. If it runs at full capacity, it will consume nearly 5 million tons of standard coal every day. After all, the mineral resources that Mother Earth can provide us are limited. The resources of our generation cannot be exhausted. Should we leave some for future generations?

Smart Americans understand the energy crisis earlier than we do. After World War II, all countries are vigorously developing their economies, especially the Middle East Gulf countries, which have exploited a large amount of underground oil for export. Americans, on the other hand, no longer exploit local oil and coal (except Alaska, which is not connected with the United States), but seal up oil fields and coal mines and import a lot of cheap oil and coal from Arab countries in the Middle East. Imagine that one day the oil in the Middle East is exhausted, and American oil will be very precious. There is no shortage of coal, but the price of electric coal has risen from less than 200 yuan /T in 2004 to more than 400 yuan /T (this is the official price, but this price can't buy coal); The actual market price is 700 yuan /T, and the thermal power plant loses electricity once. It seems that the coal price exceeds 1000 yuan /t just around the corner. For straw (taking corn as an example), the calorific value of each kilogram of dry corn straw can reach more than 3700 calories, and every two tons of straw tops one ton of coal. In the agricultural counties in the eastern plain of China, if a county has 2 million mu of land, each mu of land can produce one ton of straw every year, which is 2 million tons of straw every year. It is equivalent to an annual output of 6,543,800 tons of coal in a coal mine. Isn't it a pity that such a large part of resources have been abandoned? ! Therefore, it is an effective way for Taihua to make full use of crop straw and various renewable biological resources to save China's mineral resources.

In order to promote the development of biomass power generation technology, since 2003, the state has successively approved three demonstration projects of straw power generation in Jinzhou, Hebei, Shanxian, Shandong and Rudong, Jiangsu, which opened the prelude to the construction of straw power generation in China. With the promulgation of the Renewable Energy Law and the implementation of relevant supporting policies such as preferential feed-in tariff for biomass power generation, biomass power generation, especially straw power generation, has developed rapidly. According to incomplete statistics, by the end of 2006, there were 34 crop straw power generation projects under construction in Shandong, Jilin, Jiangsu, Henan, Heilongjiang, Liaoning and Xinjiang, with a total installed capacity of about 6.5438+0.2 million kilowatts. Three power stations have been put into operation in Shanxian, Jiangsu, Suqian and Weixian, Hebei, with a total installed capacity of 80,000 kilowatts.

In the years around 2008, large state-owned, private and foreign-funded enterprises such as State Grid Corporation and five power generation groups invested in the construction and operation of biomass power generation industry in China. By the end of 2007, the national and provincial development and reform commissions had approved 87 projects with a total installed capacity of 2.2 million kilowatts. There are more than 15 biomass direct-fired power generation projects in China, and more than 30 projects are under construction. It can be seen that China's biomass power generation industry is developing better and better.

According to the development goal put forward in the 11th Five-Year Plan, the installed capacity of biomass power generation will be 5.5 million kilowatts in the future, and the published medium-and long-term development plan of renewable energy also puts forward the development goal of biomass power generation of 30 million kilowatts by 2020. In addition, the state has decided to arrange funds to support the construction of industrial service systems such as renewable energy technology research and development, equipment manufacturing and testing and certification. Generally speaking, biomass power generation industry has broad development prospects.

China has made substantial progress in straw power generation. Vigorously developing straw power generation can not only reduce the pollution caused by a large number of burning and discarding in the field, but also turn waste into treasure and harm into benefit, which plays an important role in solving the "three rural issues" and promoting local economic development. It is estimated that building a 25,000 kW straw power plant will consume 200,000 tons of straw every year. According to the purchase price per ton of straw in 200 yuan, it will increase the income of local farmers by about 40 million yuan, benefiting nearly 50,000 households, which is an important measure to develop rural economy and increase farmers' income.

China implements preferential electricity price policy for straw power generation. The on-grid electricity price is 0.25 yuan/kWh higher than that of coal-fired power generation, and it can also enjoy a series of policies such as tax reduction and exemption. With the continuous improvement of China's related supporting policies, the progress of straw power generation technology and the formation of raw material collection, storage and transportation system, China's straw power generation industry will surely achieve faster development and make due contributions to solving the "three rural issues" and building a new socialist countryside.

China has a broad market for using straw to generate electricity.

The development and application of biomass straw power generation technology has attracted the attention of governments and scientists all over the world. Many countries have made corresponding plans, such as "Sunshine Plan" in Japan, "Energy Farm" in America and "Green Energy Factory" in India. Biomass straw power generation technology is regarded as the key project of developing renewable energy strategy in 2 1 century. According to the goal proposed in the Outline of New and Renewable Energy Development in China, by 20 10, the installed capacity of biomass power generation in China will exceed: 3 million kilowatts. Therefore, the central and local governments have formulated a series of subsidy policies to support the development of biomass energy technology and accelerate the process of technology commercialization. With the rapid development of China's national economy and the continuous improvement of the living standards of urban and rural people, the utilization prospect of straw power generation technology with economic benefits, social benefits and environmental protection will be broader and broader.

There are abundant straw resources in rural areas of China. The main crops are rice, wheat, corn, beans, potato oil crops, cotton and sugarcane. According to China's geographical distribution and climatic conditions, the southern region is rich in water resources and the temperature is high, which is suitable for the production of crops such as rice, sugarcane and oil, while the northern region is suitable for the growth of corn, beans and potatoes because of the large temperature difference between the four seasons, so the planting area is larger than other regions. Wheat is widely planted in various regions of China, with the largest sown area in Central China and East China. Cotton is mainly produced in East and Central China, followed by North China and West China. It is estimated that during the period of 2000-20 10, the annual available amount of straw resources in China will be 350-370 million t, equivalent to10.70 billion tce. If these straw resources are used for power generation, it is equivalent to 90 million kilowatts of thermal power units running for 5,000 hours a year and generating 450 billion kilowatt hours a year.

China began to introduce advanced technology from the world, and began to implement demonstration projects of biomass power generation projects.

The utilization mode of direct combustion of crop straw for heating and power generation is a feasible technical route to convert straw into biomass energy. If the demonstration of straw direct-fired heating power generation is successful, it will become the largest agricultural support project in China, the largest energy-saving and environmental protection project, and the most likely renewable energy project in China. It is precisely because the straw direct-fired power generation project has the above characteristics that it may solve the problems of tight coal supply and rising price faced by many enterprises. China straw power generation demonstration project has attracted great attention from domestic and foreign industries.

The joint venture between large enterprises in China and Danish BME company is ready to go.

Longji Electric Power Co., Ltd., jointly operated by China Longji Electric Power Technology Co., Ltd. and Beijing An Deyu Investment Co., Ltd., is the only platform for BWE "ultra-supercritical boiler", "biomass energy power generation" and other core technologies, boiler equipment related technologies and their updating technologies to enter China. Longji Electric Power Co., Ltd., as the project development company and window company of BWE in China electric power field, will invest in the production of world-advanced power plant equipment in China, gradually introduce BWE's biomass power generation technology into China, and produce BWE's biomass power generation boilers and all supporting equipment in China.

Biomass power generation project has been included in the national demonstration project.

The National Development and Reform Commission has officially approved the biomass straw power generation projects in Jinzhou City, Hebei Province and Shanxian County, Shandong Province as national demonstration projects (documentNo. [2004]20 17, Development and Reform Energy [2004]20 18), aiming at perfecting technology, standardizing and cultivating the market and forming new industries in the demonstration. This officially makes the popularization of straw power generation technology in China embark on the fast lane of new rural energy utilization.

Two demonstration projects in Jinzhou, Hebei (1×25MW) and Shanxian, Shandong (1×24MW) will introduce the world-advanced straw power generation technology of Danish BWE company. Longji Electric Power Co., Ltd., as a project investment and project implementation unit, has done a lot of preliminary research in the local area, striving to create a new road in line with China's national conditions on the basis of absorbing Danish BWE advanced technology. If the two demonstration projects are successful, it will bring unprecedented new energy revolution and huge economic benefits to the vast rural areas of China. For example, the Jinzhou project in Hebei Province burns more than 200,000 tons of straw every year and generates 65.438+0.38 billion kWh of electricity. According to the purchase price per ton of straw 100 yuan, it will drive farmers to increase their income by more than 20 million yuan/year; Compared with coal-fired power plants of the same scale, it can save more than 10000 tce a year.

In addition to the above two demonstration projects, counties (districts) rich in biomass energy resources such as Rudong County in Jiangsu, Qing 'an County in Heilongjiang and Pinggu District in Beijing are actively negotiating with Longji Electric Power Co., Ltd. to start construction of straw power plants.
