PCT No. PCT/JP85/00466 Sec. 371 Date Mar. 19, 1986 Sec. 102(e) Date Mar. 19, 1986 PCT Filed Aug. 23, 1985 PCT Pub. No. WO86/01579 PCT Pub. Date Mar. 13, 1986.A waste heat recovery boiler for a turbine including two denitrating devices disposed in the boiler to reduce the NOx concentration in an exhaust gas below a pre-determined value even when a turbine load changes. The overall denitration efficiency distribution of the boiler with respect to the turbine load can be set arbitrarily by selecting suitable positions of the denitrating devices and the amounts of a catalyst, and any adverse effects resulting from the change of the turbine load can be avoided.
