原始语种摘要: This paper introduces the technological process and operation mode of denitrification and ammonia supply in coal-fired power plants. The Selective Catalytic Reduction (SCR) flue gas denitrification technology of coal-fired power plant is a great significant to environmental protection, which denitrification efficiency is up to 90%. A coal-fired power plant SCR boiler flue gas denitrification device of ammonia controlling valves often block in the winter, and need stopping the device to carry out manual cleaning, that seriously affecting the normal operation of the SCR system and NOx emissions standards. Through the mothed of analyzing of the physical scale components of liquid ammonia quality, environmental temperature, equipment, material, jam, we had found the causes of the problem....
