摘要： A heat recovery system includes a preheater (4) in which heat exchange is performed between condensed water generated in a condenser (3) and CO 2 in a CO 2 recovery apparatus, a gas heater (5) in which heat exchange is performed between the condensed water heated in the preheater (4) and exhaust gas discharged from a boiler (7) and the boiler (7) to which the condensed water heated in the gas heater (5) is supplied as boiler supply water. With this configuration, an amount of steam extracted from a low-pressure steam turbine (2) is reduced.

摘要： In a duct leading to a chimney (10) which discharges exhaust gas to the atmosphere, an exhaust gas residual heat recovery device (1) is provided with a dry economizer (2) which uses the sensible heat of exhaust gas to heat water-to-be-heated; and a condensation economizer (4) which is provided on the downstream side of the dry economizer (2), and uses the condensation latent heat of exhaust gas to heat the water-to-be-heated. The duct comprises a first stage duct (6) wherein the dry economizer (2) is provided, and a latter stage duct (8) which is connected to the first stage duct (6), and changes exhaust gas flow into rising flow. The condensation economizer (4) is installed in the latter stage duct (8). The configuration of the duct is such that the exhaust gas reaches the condensation temperature in the vicinity of an upper section (5) of the condensation economizer (4).
