Description of the Related Art A raw fuel such as coal, heavy oil, orimuljeon is partially oxidized into a gasified fuel, which is used as a fuel for a gas turbine or the like. However, when the raw fuel contains a large amount of water or is used after adding water, the obtained gasified fuel has a high temperature of several 100 ° C. or higher and contains a large amount of water vapor and a sulfur compound such as hydrogen sulfide. I'm out. When desulfurization treatment is carried out by bringing the gasified fuel into contact with an amine-based absorption liquid, it is necessary to further cool the gasified fuel to near normal temperature to absorb acid gases such as hydrogen sulfide and carbon dioxide. Therefore, since the high temperature gasified fuel is cooled by the heat exchanger using the cooling water, the heat of condensation when the steam becomes water is wasted to the cooling water side.
