PROBLEM TO BE SOLVED: To improve the efficiency of an entire system. SOLUTION: Ash-melting facilities consisting of an ash-melting furnace 4 for thermally decomposing waste for gasification, burning and melting a thermal decomposition gas at a high temperature, and collecting ash content as a molten slug, and cooling water systems 17 and 18 for performing cooling by circulating and supplying the cooling water to the ash-melting furnace, steam turbine power generation facilities consisting of a steam turbine power generation system for generating power by supplying steam from a boiler to a steam turbine 8 where a generator is directly connected, condensate systems 9 and 10 for recovering steam that is inflated by the steam turbine for working as condensate after cooling and condensation and for creating water being supplied to the boiler, water supply systems 11 and 12 for supplying water from a condensate system to the boiler again after heating and deaeration treatment as needed, and a cooling water system for cooling by circulating and supplying cooling water from a cooling tower 1 to each kind of equipment for power generation facilities of the steam turbine power generation system, and a heat exchange means 13 for cooling the cooling water of the ash-melting facilities by exchanging heat with condensate in the steam turbine power generation facilities.
