Abstract
High temperature of flue gas can decrease the efficiency of boiler and power plant.The main factors influencing the temperature of flue gas,such as air leakage into furnace,proper burning in the furnace,the operating mode of coal pulverizating system,the amount of the cold air is analyzed and the corresponding measure is put forward.The operation shows that the temperature of flue gas is reduced by nearly 20 ℃ and the efficiency of boiler rose by 1%.
