Abstract
PURPOSE: To prevent the increase of dust concentration of treating gas, by introducing a heat accumulating body obtained in the first heat exchanger into the second heat exchanger after bringing the body into contact with heated air to peel off attached dust in a preliminary step.
CONSTITUTION: Waste gas 2 from a coal-fired boiler 1 is introduced into the first heat exchanger 12 through an electrostatic precipitator 3, a denitration apparatus 5, and an air preheater 7. Waste gas 13 reduced to low temperature in the exchanger 12 enters the second heat exchanger 16 through a wet waste gas treating apparatus 14 and is reheated to be discharged into the atmosphere from a chimney 18. A heat accumulating body, after receiving heat energy from untreated gas at the first exchanger 12, is introduced into the 1' heat exchanger 19 in a preliminary step to bring it into contact with heated air 25 in order to peel off attached dust, and then is introduced into the second exchanger 16; thus the increase of dust concentration of waste gas 17 is prevented. Next, the body reduced to low temperature is returned to the first exchanger 12 after being sent to the 2' heat exchanger 20 to bring it into contact with heated air 26 from a heat exchanger 19.
