China's first set of flue gas ultra-low emission devices was put into operation at Unit 8 of Zheneng Jiaxing Power Plant. After the technical transformation of the million-kilowatt coal-fired unit, its main pollutant discharge is comparable to that of the natural gas gas turbine unit, reaching the international advanced level, opening a new era of clean emissions of coal-fired generating units, and developing the economically developed areas in the east. The development of coal-fired power has opened up new avenues and has important strategic significance for safeguarding China's energy security.
After preliminary testing, the emission index of the device meets the design requirements after it is put into operation.
In order to earnestly fulfill the social responsibility of environmental quality and public health, Zhejiang Energy Group Co., Ltd. has continuously self-pressurized on the basis of meeting the current national emission standards, and took the lead in implementing the “super-low emission of flue gas from coal-fired units†in national power generation enterprises. Work, continue to increase the pace of clean production, on the basis of meeting the current national emission standards, increase the promotion and application of clean coal power and energy-saving environmental protection technology. After the implementation, the main pollutants from the coal-fired power plant emissions will reach the emission standard of natural gas-fired gas turbines with clean power generation, that is, the smoke does not exceed 5 mg/m3, the sulfur dioxide does not exceed 35 mg/m3, and the nitrogen oxides do not exceed 50 mg/cubic. M., the emission standards of soot, sulfur dioxide and nitrogen oxides in key areas specified in the “Air Pollutant Emission Standards for Thermal Power Plants†(GB13223-2011) decreased by 75%, 30% and 50% respectively.
Jiadian's million kilowatt coal-fired unit flue gas ultra-low emission renovation project is the first demonstration project to implement ultra-low emission in the country. The total investment of the project is 395 million yuan. Through the demonstration and transformation of two million kilowatt coal-fired units that have been put into operation, the “multi-contaminant efficient synergistic removal integrated technology†is adopted to make the main pollutant emission index of coal-fired units. Meet or exceed the gas unit emission standards. The project was started on August 13, 2013.
Zhejiang Energy Group took the lead in implementing ultra-low emission demonstration and transformation in the country, and innovative coal clean combustion and clean emission technologies will open up new space for the entire coal-fired power generation industry and bring new development opportunities.
It is also known that the ultra-low emission renovation project of Jiadian No. 7 unit has also entered the commissioning phase and will be officially put into operation in the near future.
