What does China rely on to generate electricity if it does not rely on wind or water?

Aspect 1

The "gas" that was once talked about in disgrace has now become a model of clean energy thanks to the magical gas engine

China Shipbuilding Industry Corporation After thousands of experiments, its subsidiary Hechai Heavy Industry finally produced a high-speed diesel engine. Not only did it mean that Chinese warships would be equipped with their own "Chinese heart", causing a sensation in the world, but they also broke through another technology, that is, large-scale Gas engine. Most of the buses and taxis we usually take use gas engines. Gas engines can not only use natural gas, petroleum gas, and coal bed methane as energy, but also use biogas and landfill gas. In the mountains of Guizhou, they applied the gas engine they developed in a special power station.

China’s gas utilization level is the world’s leading and the economic benefits are surprising

At eight o’clock in the morning, although it was drizzling, Wenjiaba Deng Hong, the director of the power station, still conducted routine safety inspections with two employees. This power station located deep in the mountains of Guizhou does not rely on wind power, water power, or coal. The energy that drives it comes from gas buried deep underground. The generating units here also come from China Shipbuilding Industry Group Hechai Heavy Industry .

The scientific name of "gas" is coalbed methane. The main component is methane and exists between coal seams. According to various news reports, mines often explode due to leaked gas ignited by open flames, resulting in loss of life and property, so that people become disloyal when talking about "gas". In fact, because its main component is methane, it will only emit water and carbon dioxide after full combustion and utilization, so gas is still a clean energy source that can be mined.

Wenjiaba Power Station has installed four gas-fired generating units. Ren Xiaohui made a special trip from Luoyang to conduct a two-month operation inspection.

Ren Xiaohui, chief technical engineer of gas engine design at China Shipbuilding Industry Group Hechai Heavy Industry: This machine has now been running for 1,476 hours and has a total power generation of 1.04 million kilowatt hours.

Ren Xiaohui said that these four gas-fired generator sets were independently developed by Hechai Heavy Industry of China Shipbuilding Industry Group and have a very high degree of automation. Even the exhaust fans and gas concentration measuring instruments are automatically operated by the control cabinet. , the daily work of employees is simple inspections, and general shutdown and startup tasks can be done by just moving your fingers on the touch screen and buttons. In addition, it also has a world-leading technology.

Ren Xiaohui said that in the global gas power generation industry, foreign countries burn high-concentration gas and evacuate all low-concentration gas. In China, all low-concentration gas is utilized. Hechai generating units use low-concentration gas. Generator units can burn about 10% of gas, and the concentration value of gas utilization is already leading in the world.

If gas gas is discharged directly into the atmosphere, the pollution caused will be 21 times that of carbon dioxide. The gas used for power generation today not only has good environmental benefits, but also has considerable economic benefits.

Meng Haitao, general manager of Guizhou Water Mine Orian Clean Energy Co., Ltd.: The gas power station is still very efficient. In the past two months, the total power generation has been close to 3 million kWh, and the daily power generation is About 50,000 to 60,000 kWh. We calculated that its profit margin can reach 30%.

Meng Haitao told us that the country has corresponding policies on gas power generation. First, we must ensure that the coal mines are used by ourselves, and then use the surplus to access the Internet. At present, the Wenjiaba gas power station can meet 50% of the coal mine's electricity consumption. When the two power stations are built in the future, there will be a surplus of electricity. At that time, electricity will solve the electricity problem of residents in the mountains. Calculated based on the average electricity consumption of three kilowatt hours per household per day, their daily power generation capacity is now close to 60,000 kilowatt hours, which can be used by 20,000 households.

After inspecting the generating units in Guizhou, Ren Xiaohui worked non-stop. He had to fly back to Luoyang as soon as possible. There was a special "big test" waiting for him at the gas engine test site.

Carbon and lead emissions dropped by 80% after the domestic gas engine was put into use

In the gas engine test site, the China Classification Society’s inspection Captain Ma Beizhan and Ren Xiaohui were carefully inspecting every part of the gas engine in front of them, not missing any subtle changes in operation. Ma Beizhan told us that testing and certification of an engine requires tracking from the processing of parts.

China Classification Society is the only professional organization engaged in ship classification inspection business in China. Every ship engine must be inspected and approved by the Classification Society before leaving the factory. Ma Beizhan has eight years of experience in testing and acceptance. He has tested and certified thousands of engines, but this is the first time he has inspected and accepted this high-speed and high-power gas engine, so he is particularly serious. Although the noise of the engine reached 100 decibels, Ren Xiaohui still carefully explained various indicators and parameters of the gas engine to Ma Beizhan through gestures and words.

Ren Xiaohui, chief technical engineer of gas engine design at China Shipbuilding Industry Group Hechai Heavy Industry: Compared with diesel engines and gas engines, gas engines have a 100% reduction in nitrogen and oxygen emissions, including carbon dioxide, including carbon and lead emissions, compared with diesel engines. Fifty to eighty percent.

Ren Xiaohui said that this high-speed and high-power gas engine is a gas engine developed on the basis of the 622 diesel engine. It is the most advanced in the country and among the top levels in the world. It will be inspected and certified after completion. I am going to attend the Maritime Conference held next month.

Liu Piren, Chairman and Party Secretary of China Shipbuilding Industry Group Hechai Heavy Industry: Enterprise development must have many factors that promote the growth of an enterprise, and the technical advantages of products are a very important part of it, because product development Innovations in technology and technology are the driving force for an enterprise's internal improvement. If the products can be continuously planned, produced and developed well, then the enterprise's stamina will be relatively large.

Point 4

The road to independent innovation in the military industry will never end

From the experience of China Shipbuilding Industry Group Hechai Heavy Industry, we can see that China’s military equipment The road to modernization is quite difficult. Most of the military equipment and research and development must be done by ourselves, or even from scratch. Looking back, we are more determined and insist on independent research and development. We will not change this principle. In addition, it needs to be emphasized that although some achievements have been made in the field of military equipment in recent years, China does not rely on gunboats to open the way to develop economy and trade, but relies entirely on mutually beneficial cooperation, even cooperation that gives benefits. We have always adhered to the path of the path of peaceful development.
