    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: A wet type exhaust gas desulfurization apparatus includes an absorption tower desulfurizing exhaust gas by causing the exhaust gas to come into gas-liquid contact with an absorbent, a spray mechanism spraying the absorbent into the tower, an oxidization mechanism provided in a bottom portion of the tower and supplying oxygen to the absorbent that accumulates inside the tower, a circulation mechanism feeding the absorbent from a discharge port formed in the bottom portion of the tower, to the spray mechanism, and a liquid ejection mechanism including a hydraulic nozzle ejecting liquid into the tower. In this apparatus, the oxidization mechanisms are provided with an interval in a horizontal direction relative to the discharge port. Furthermore, in the apparatus, the hydraulic nozzle is installed in the bottom portion of the tower and is provided at a location between the oxidization mechanism and the discharge port.
