H 2 S is an important element to high-temperature corrosion for the water-cooled wall of coal-fired boilers, thus, it is an effective means to prevent high-temperature corrosion through reducing the concentration of H 2 S near the boiler wall. Since the concentration of H 2 S in the boiler is closely related to the concentration of O 2 and CO, the research on the distribution of H 2 S atmosphere in the boiler furnace was conducted in this paper. With the air distribution regulation as the means, local O 2 concentration is increased, to avoid the accumulation of H 2 S near the wall and reduce high-temperature corrosion.
