PURPOSE:To effectively recover not only the sensible heat of exhaust gas but also the condensed latent heat of steam contained in exhaust gas and to improve the coefficient of heat recovery, by a method wherein the interior of the combustion system and the exhaust gas of an incinerating device is maintained in a pressurized condition. CONSTITUTION:Two compressers 19 and 20 are mounted to an air passage 8 for combustion, and two turbine 21 and 22, positioned corresponding to the compressers, are installed to an exhaust gas passage 11. A first heat exchanger 23 for recovering mainly the sensible heat of high temperature exhaust gas exhausted is installed in the vicinity of an exhaust gas outlet 10 of an incinerator, a dust collector 12 and the turbine 21 are located on an exhaust gas passage 11 on the downstream side thereof, and a second heat exchanger 24 for recovering the condensed latent heat of steam contained mainly in exhaust gas is situated on the downstream side thereof. This constitution enables exhaust gas from an incinerator 2 to be heat-exhanged with a heating medium within the first heat exchanger 23 to recover the latent heat. Exhaust gas exhausted from the first heat exchanger 23 is released from part of its pressure through the dust collector 12 and the turbine 21, and is further introduced in the second heat exchanger 24 where the sensible heat of exhaust gas and the condensed latent heat of steam are recovered. |
