Abstract

Abstract: Traditional energy coal is still one of the main power generation units in China, so in order to improve the thermal efficiency of boiler and reduce the emission of nitrogen oxide, this paper takes the 200MW tangent round boiler of a power plant as the research object, On the basis of the original boiler, the simulation analysis of the boiler before and after retrofitting is carried out under the condition of boiler maximum continuous rate (BMCR). The temperature field in boiler center position and the distribution of NO, CO in furnace before and after retrofitting is compared. Comparing with the curve of NO, it can be found that the concentration of NO at the outlet of the retrofitting boiler is lower than that of the former, and the effect of boiler retrofit is obvious.
