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 CO2 in a CO2 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： There is provided an exhaust gas treatment system including a CO2 recovery unit with further enhanced energy efficiency. An exhaust gas treatment system (1) of the present invention includes: a CO2 recovery unit (10) including a CO2 absorption column (11), an absorbing solution regeneration column (16), and a reboiler (21); and an exhaust gas heat exchanger (5) provided on a gas upstream side of the CO2 recovery unit (10). Heat exchange is performed between process condensate discharged from the CO2 absorption column (11) and steam condensate discharged from the reboiler (21) in a heat exchanger (22). The heated process condensate is fed to the absorbing solution regeneration column (16). Heat exchange is performed between the cooled steam condensate and exhaust gas in the exhaust gas heat exchanger (5) so that the steam condensate is heated while the exhaust gas is cooled.
