The implementation of the new standard of air poll

The new standard of air pollution emission of China's thermal power implemented the ultra-low emission of coal and electricity exploration

in July, the new standard of air pollution emission of China's thermal power, known as the "strictest in history", began to be implemented. With this environmental protection "hoop curse" overhead, many Chinese coal and power enterprises began to explore the ultra-low emission of natural gas standards. In July, the new emission standard of air pollution from China's thermal power plants, known as the strictest in history, began to be implemented. Many of the environmental protection hoop mantras above are ideal materials for manufacturing supercapacitors. Chinese coal and power enterprises have begun to explore the ultra-low emission of natural gas standards, trying to get rid of the stereotype of the black and dirty coal industry

ultra low emission or ultra clean emission refers to that the flue gas emission of coal-fired units after the completion of transformation meets the standards of natural gas units, that is, sulfur dioxide does not exceed 35 mg/m3, nitrogen oxide does not exceed 50 mg/m3, and soot does not exceed 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 regions. Zhejiang, Jiangsu, Guangdong and Shandong, which are located in developed coastal areas, have also recently explored ways to transform coal-fired power plants into ultra-low emission ones. Against the background of China's efforts to speed up the control of smog and eliminate the suffering of the people's hearts and lungs, China's coal-fired power generation industry, which has been accused of being the culprit of smog for a time, has entered an era of ultra-low emissions

units 7 and 8 of Jiaxing Power Plant Phase III, Shenhua Guohua Zhoushan power plant unit 4 and Guangzhou Hengyun 300000 kW coal-fired unit 9 under Zhejiang energy group have completed ultra-low emission transformation and have been put into operation recently. The ultra-low emission transformation of Datang Nanjing power plant is scheduled to be completed by the end of this year. Huaneng Zibo Baiyanghe Power Generation Co., Ltd., the first pilot ultra-low emission technological transformation project in Shandong, has also entered the commissioning stage since a plastic plant was moved to the village at the end of last year, and is about to realize trial operation

Guangzhou Hengyun group is the second largest power generation enterprise in Guangzhou. Although the group has just completed the ultra clean transformation on the definition of special engineering plastics, the coal-fired unit 9 was officially put into operation recently. 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 and soot are 4 mg/m3, 25 mg/m3 and 1.94 mg/m3 respectively, which are better than the pollutant limits of the gas turbine

Wang Yanjun, chief engineer of Hengyun group, told that after the same transformation of another 300000 coal-fired units was completed in the first half of 2015, the air pollutants caused by the power generation of the two units would be reduced by more than 70% compared with the current level

according to the data of China Electric Power Construction Enterprise Association, by the end of 2013, China's installed power generation capacity had exceeded 1.2 billion kw, including 862million kW thermal power, accounting for 69.13% of the total installed capacity. The installed capacity of coal-fired power has reached 786million kW. In the Beijing Tianjin Hebei Shandong and Yangtze River Delta regions with serious haze, the installed capacity of coal and electricity per unit land area is far higher than that in the northwest region, and the air pollution emissions per unit area are more than several times of the national average in the current development of medical materials and products in the direction of scope, accuracy, personalization and intelligence

at present, many cities aim at changing coal to gas as the way to control air pollution, but they are seriously constrained by the lack of gas sources. In 2013, China's natural gas production reached 121 billion cubic meters, its apparent consumption reached 169.2 billion cubic meters, and the gap between supply and demand exceeded 50 billion cubic meters; It is estimated that this year's consumption will reach 186 billion cubic meters and 63billion cubic meters of imported natural gas, with the external dependence rising to 33.6%

despite the continuous launch of clean energy projects, the review of China's energy structure shows that coal still accounts for more than 70% of the one-time energy consumption, and thermal power generation still accounts for more than 70% of the power generation. The status of coal as the main energy and the important task of ensuring China's safe and stable energy supply are difficult to change for a long time

after the coal-fired power plant adopts ultra-low emission technology, it will first be of great significance to the implementation of the air pollution prevention and control action plan in Beijing Tianjin Hebei Shandong, Yangtze River Delta and Pearl River Delta

at present, the National Energy Administration of China is accelerating the formulation of the action plan for upgrading and upgrading coal and electricity energy conservation and emission reduction, focusing on promoting equipment upgrading and technological transformation in the coal and thermal power fields. Wu Xinxiong, director of the national energy administration, proposed that through five years of upgrading and transformation, the national average coal consumption should be reduced to 310 grams/kWh, and the emissions of coal-fired units in key areas should be close to the level of gas-fired power generation, so as to realize the clean and efficient utilization of coal
