The most stringent emission standards in history

wallpapers News 2020-06-26

entered July, the new emission stard of air pollution from thermal power plants in China, known as the "strictest in history", began to be implemented. Many enterprises are trying to get rid of the stereotype of "low emission of coal" in China.

ultra-low emission or ultra clean emission refers to that the flue gas emission of coal-fired units meets the stards of natural gas units after the transformation, that is, sulfur dioxide is not more than 35 mg / m3, nitrogen oxide is not more than 50 mg / m3, smoke dust is not more than 5 mg / m3.

it is understood that China's five major power generation groups have successively deployed ultra-low emission strategies in the eastern developed areas. Zhejiang, Jiangsu, Guangdong Shong, which are located in the coastal developed areas, have recently explored the transformation of ultra-low emission coal-fired power plants. Under the background of China's accelerating haze control striving to eliminate the "heart lung disease" of the people, China's coal-fired power generation industry, which has been regarded as the culprit of haze, has entered a "ultra-low emission era".

Zhejiang energy group affiliated Jiaxing Power Plant Phase III 7 8 million units, Shenhua Guohua Zhoushan power plant unit 4, Guangzhou Hengyun 300000 kW coal-fired unit 9 have all completed ultra-low emission transformation put into operation recently. Datang Nanjing Power Plant's ultra-low emission transformation is planned to be completed by the end of this year. Huaneng Zibo Baiyanghe Power Generation Co., Ltd., the first pilot ultra-low emission technical transformation project in Shong Province, has entered the commissioning stage is about to realize trial operation.

Guangzhou Hengyun group is the second largest power generation enterprise in Guangzhou. The group has just completed the ultra clean transformation of coal-fired unit 9, recently officially put into operation. According to the on-site sampling data of the third-party environmental monitoring, the emission values of the three main pollutants -- nitrogen oxide, sulfur dioxide smoke dust are 4 mg / m3, 25 mg / m3 1.94 mg / m3 respectively, which are better than the pollutant limits of gas turbine units. Wang Yanjun, chief engineer of

Hengyun group, told reporters that after the completion of the same transformation of another 300000 coal-fired unit in the first half of 2015, the air pollutants caused by the two units will be reduced by more than 70% compared with the current situation. According to the data of

China Electric Power Construction Enterprise Association, by the end of 2013, China's installed power generation capacity exceeded 1.2 billion kilowatts, including 862 million kilowatts of thermal power, accounting for 69.13% of the total installed capacity. The installed capacity of coal-fired power has reached 786 million kilowatts. In Beijing, Tianjin, Hebei, Shong Yangtze River Delta, the installed capacity of coal electricity per unit area far exceeds that of Northwest China, the air pollution emission per unit area is several times of the national average level.

many cities aim at "coal to gas" to control air pollution, but they are seriously restricted by the lack of gas source. In 2013, China's natural gas production reached 121 billion cubic meters, the apparent consumption reached 169.2 billion cubic meters, the gap between supply dem exceeded 50 billion cubic meters. It is estimated that this year's consumption will reach 186 billion cubic meters, the import of natural gas will reach 63 billion cubic meters, the external dependence will rise to 33.6%. Although the clean energy projects of

have been launched continuously, the investigation of China's energy structure shows that coal still accounts for more than 70% of one-time energy consumption, thermal power generation still accounts for more than 70% of power generation. The status of coal as the main energy source the responsibility of ensuring China's energy security stable supply are difficult to change for a long time. After the implementation of "spkds" "spkds" in the Yangtze River Delta the Pearl River Delta, the implementation of the "spkds" plan will be of great significance to the prevention control of air pollution in the Yangtze River Delta the Pearl River Delta.

at present, China's national energy administration is accelerating the formulation of the "coal power energy conservation emission reduction upgrading action plan", focusing on promoting the coal thermal power fields to update equipment technological transformation. Wu Xinxiong, director of the state energy administration, proposed that through five years of upgrading transformation, the national average coal consumption will be reduced to 310 g / kWh, the emission of coal-fired units in key areas will be close to the level of gas-fired power generation, so as to realize the clean efficient utilization of coal.
