PROBLEM TO BE SOLVED: To lower a temperature of high-temperature exhaust gas within a limit of the heat resistance of a latent heat recovery heat exchanger formed of titanium without using a heat exchanger for a high temperature while effectively utilizing the sensible heat of the high-temperature exhaust gas.SOLUTION: The high-temperature exhaust gas is sprinkled at an inlet side or an outlet side of the latent heat recovery heat exchanger, the sprinkled water is heated by the heat of the exhaust gas to be water vapor, and the gas temperature is lowered. The water vapor generated by sprinkling water is condensed together with the original water vapor of the exhaust gas by taking advantage of characteristics of a latent heat recovery device. The increased condensation latent heat is also utilized for water supply to a boiler, for example, as high-temperature water. |
