摘要
A thermal power plant for recovering water from exhaust gas comprising: a gas turbine; a heat recovery steam generator for generating steam by supplying exhaust combustion gas exhausted from the gas turbine as heat source; a water recovery system installed on the downstream side of the heat recovery steam generator for condensing and recovering water in the exhaust combustion gas through direct gas/liquid contact between the exhaust combustion gas coming down from the heat recovery steam generator and water; a recovered water system for supplying a part of the water recovered by the water recovery system, thereby allowing the water to be circulating as circulating water; a feed water system for supplying the heat recovery steam generator with other part of the water recovered by the water recovery system as feed water; a first pH adjusting system installed in the recovered water system to adjust the circulating water flowing through the recovered water system to a first pH value (hydrogen ion concentration index); a second pH adjusting system installed on the feed water system to adjust the feed water flowing through the feed water system to a second pH value (hydrogen ion concentration index); and a control system for controlling the volumes of the pH adjusters supplied from the first pH adjusting system and the second pH adjusting system.
