With the increasingly serious environmental pollution, our daily lives are affected seriously; the environment of management has become highly necessary. A variety of coal-burning emissions vented into the atmosphere lead to the pollution of the environment, and the main pollutant is the acid gas emissions. The coal consumption and emissions are large in the power industry, therefore, it is a focus to reduce emissions of SOx and NOx the coal-fired power plants for the management of the environment.In this paper, it was analyzed and researched that running cost of the denigrations and desulphurization in the thermal plant of soot. Firstly, the model that calculated running cost of the denigrations and desulphurization was founded in the thermal plant. Secondly calculated and analyzed the running costs of denigrations and desulphurization basing on SCR and FGD methods. Called on people to conserve energy, reduce emissions, in order to protect our environment truly.
