Thermal Power Plant Air Pollutant Emission Standard

The Ministry of Environmental Protection and the State Administration of Quality Supervision jointly issued the newly revised "Emission Standards for Air Pollutants from Thermal Power Plants", which will be implemented as of January 1, 2012. Tao Detian, a spokesperson for the Ministry of Environmental Protection, revealed today that through the implementation of the new standards, while significantly reducing pollutant emissions, it can also promote the development of environmental protection technologies and industrial markets, and create a total of approximately 2600 environmental protection and equipment manufacturing industries such as denitrification, desorption, and dust removal. Billion market size.

Wu Xiaoqing, vice minister of the Ministry of Environmental Protection, said that compared with the old standard in 2003, the new standard drastically tightened the emission limits of nitrogen oxides, carbon dioxide*, and soot, and formulated more stringent atmospheric pollutants for key and environmentally sensitive areas. Special emission limits and additional mercury and gas boiler emission limits. In addition, corresponding emission control requirements have been stipulated separately for existing and new thermal power construction projects. Among them, for the new thermal power plant, strict pollutant emission limits are stipulated; for the existing thermal power plants, a two-and-a-half year standard discharge transition period is set up, and the enterprises are to be rebuilt for a certain period of time. Each control limit in the new standard has a corresponding mature and reliable control technology, and it is stipulated that the removal and dedusting should be considered as a whole, so that the control of emission of atmospheric pollutants from thermal power plants forms an organic whole.

Wu Xiaoqing said that the implementation of new emission standards requires the thermal power industry to increase investment in environmental protection. Overall, the resulting emission reductions and environmental benefits are at a reasonable level compared with the investment intensity of companies. It is estimated that by 2015, the capacity of existing units and new units to be removed for removal of nitrogen oxides will be approximately 817 million kilowatts, which will require an investment of approximately 195.0 billion yuan, and an annual operating cost of approximately 61.2 billion yuan; dust removal and removal facilities. The reconstruction and new investment costs will cost about 65 billion yuan. The company's compliance expenditure can be compensated through the preferential electricity price policy.

It is reported that in 2009, China's total emissions of nitrogen oxides and carbon dioxide* were 1692.7 and 22.144 million tons, respectively. The emissions of nitrogen oxides and carbon dioxide* from the power industry accounted for about 49% and 46.4% of the country's total emissions. After the implementation of the new standard, by 2015, the nitrogen oxides and dioxide* in the power industry can be reduced by 580,618 tons. In addition, the implementation of the new standard also has significant emission reduction effects on particulate matter, mercury and other pollutants in the power industry.
