| With the rapid development of industrialization in our country, environmental pollution has turned out to be a serious problem that influence our daily life. Especially the pollutants emission of factory, which directly accelerated the deterioration of air quality. In recent years, national and local government have successively introduced environmental management standard, to specific clearfy the standard of power plant nitrogen oxides emission. In order to encourage the management of each power plant to environment pollution, positive guidance has been made by the government in power distribution plan, denitration electricity price compensation, and funds compensation at various levels. In this background, denitration modified became the urgent problem that need to be solved in power plant project. Adai sea power plant as a large state-owned enterprise, must take the social responsibilities, and also in this case, adai sea power plant decided to modifiy NO.2 unit to denitration environmental renovation.At present, many researches focused on denitration modified technology. However, through comprehensive comparison, adai sea power plant decided to choose composite plan include low NOX burner modified and flue-gas denitration project. This scheme can effectively control the NOX content in smoke less than 100 mg/Nm3.In this paper, combining with the current practical situation of the NO.2 unit in adai sea power plant, relying on the existing site, equipment, manpower and other basic conditions, through comparative study of all kinds of denitration technology and scheme, the feasibility of denitration technology, denitration process, and environmental and economic benefits was analyzed, and a supervision plan scheme of denitration modification was established for NO.2 unit. |
