Application of arc sprayed nickel-chromium-molybdenum alloy material in thermal power plant desulfurization flue anticorrosion

       

Flue gas desulfurization (FGD) is the removal of sulfur oxides from gaseous products produced during the combustion of fossil fuels. Traditional combustion technology oxidizes most of the sulfur in the fuel and emits it into the flue gas, contributing to the formation of "acid rain". "Acid rain" generally refers to the deposition of various acids in the atmosphere, which can cause damage to the environment and human health. Acid rain has become a major concern for governments around the world Energy saving and low-sulfur fuels to replace high-sulfur fuels have played a role in reducing overall pollution, but technologies to remove sulfur oxides are still necessary. At present, alkaline slurry such as lime/limestone slurry is mainly used for wet washing process
