Abstract

PURPOSE: To maintain the temperature of exhaust gas which is fed to a denitration apparatus at a fixed temperature by arranging a bypass line in which the control of flow rate is enabled between the inlet side and outlet side for heat exchanging fluid.
CONSTITUTION: Between the inlet side water feeding pipe 2 and the exit side water feeding pipe 14 of a heat exchanger 3 arranged inside the cage wall 4 of an exhaust gas duct, a bypass line 12 equipped with a valve 13 is arranged, and in the exit water feeding pipe 2, a valve 11 is arranged. When the load of a boiler is below 50%, the temperature on the gas downstream side lowers, so that bypass valve 13 is opened, and when necessary, the valve 11 is closed to reduce the feeding water amount to the heat exchanger 3, and the temperature of the exhaust gas which is fed to a denitration apparatus is controlled always to be above 330°C.
