High temperature corrosion on water wall is easily caused by burning high sulfur coal in low nitrogen burner of boilers in power station. Based on the combustion adjustment test of 600 MW unit boilers, this paper introduces the technical means of burner air distribution and coal mill operation optimization under low nitrogen combustion mode, realizes the optimal distribution of aerodynamic field in reductive and oxidative zones of boilers, and achieves the balanced control of boiler safety, environmental protection and energy saving when burning high sulfur coal. This technical means can provide reference for the operation of other similar boilers.
