The Feasibility Study Of The A Coal-fired Power Plant Wet Electrostatic Precipitator Retrofit Project

According to the national environmental protection file, the thermal power plant air pollutant emission standards(GB13223-2011) limit requirements and the Guangdong province sewage permit management approach, coal-fired power plants must be in accordance with the requirements of the document, which is the key areas of the Pearl River Delta region should be strictly more stringent standards, otherwise it will be suspended sewage. A coal power plant at present, #4, #3 unit flue gas emissions can not meet this requirement, especially mercury and its compounds, is the new monitoring standards, the existing equipment verification to remove. A power plant must carry out research, carry out environmental protection equipment to upgrade or reform to meet the requirements of environmental protection policy. At the same time, in order to ensure the protection of environmental protection has a certain forward-looking, A coal fired power plant to advance the implementation of flue gas pollutants near zero emissions". To achieve "near zero emissions", so that soot, sulfur dioxide, nitrogen oxide emissions concentrations reached or below the current emission limits of gas turbine.Therefore, for a power plant revamping projects of environmental protection were feasibility study, through theoretical research and actual unifies, access to documents, on-site diagnostic evaluation method, and the characteristics of coal power plant coal to a fuel, boiler system electric precipitator and desulphurization system operation status is evaluated, that should be added precipitator conclusion, and through the technical feasibility of the reconstruction technology analysis, economic feasibility analysis, implementation to demonstrate the feasibility of. The main problems of the new type of wet dust collector is the following main problems: the problem of air pollutant dust emissions, the removal of the sub micron dust(PM2.5), the removal of GGH and the removal of heavy metals.Through the implementation of the project, the A power plant chimney emission can achieve lower emissions, and realize the "near zero emissions" goal. Can bring good environmental benefits and social benefits for the enterprise.
