Study on the Influence of Wall Air on the Reducing Atmosphere Near the Wall of the Boiler
Most of the active coal-fired power station boilers in China adopt low NOX combustion technology,which leads to frequent high temperature corrosion in the furnace,which has seriously affected the safe and stable operation of the units.In this paper,the influence of wall wind on reducing gas(H2S,CO)on the near wall is studied through field tests.The results show that the front wall,side wind front wall and side wall wind can effectively reduce the concentration of H2S and CO in the main combustion area and exhaust area of the furnace.For the cold ash bucket area,there is no significant effect after the primary wind wall wind and rectangular nozzle secondary wind wall wind operation.
