<p>PURPOSE:To discharge exhaust gas from a smoke stack in a condition free from white smoke by a method wherein exhaust gas is fed to a reheater and the heat of the exhaust gas is fed from the reheater to a white smoke preventing device. CONSTITUTION:A reheater 21 is provided along a reheater pipe 27 for conducting exhaust vapor from a high pressure side turbine 15 to a low pressure side turbine 16. A white smoke preventing device 14 is provided along an exhaust gas passage 10 for conducting exhaust gas from an incinerator 1 to a smoke stack 11. A superheater exhaust gas feed passage 36 is provided to feed exhaust gas from a combustion superheater 20 to the reheater 21 and a white smoke preventing air feed passage 31 is provided to feed the heat of exhaust gas from the reheater 21 to the white smoke preventing device 14. By the aforesaid arrangement, the exhaust gas from the incinerator can be discharged from a smoke stack in a condition free from white smoke.</p> |
