| At present the general problems such as temperature corrosion of water wall and gas temperature deviation do exist among Power Plant in Neimeng region, which brings much harm to safety and economical operation of boiler. The reason of the high temperature corrosion of water wall of No.1 boiler of some Power Plant is the coal problem and separation of primary and secondary air. In order to reduce the gas temperature deviation, the key is in reducing residual rotation and shortens the flame length. According to the results of cold model test and numerical simulation of this paper, the reasonable scheme is got. The result shows that the scheme of this paper can resolves the high temperature corrosion and gas temperature deviation problems. Zhao Bing (Thermal power engineering) Directed by prof.
