Abstract
A combustion gas cooling apparatus includes a cooling duct from which a cooling gas at a temperature lower than the temperature of a combustion gas flows out into a mixing duct to form a mixed gas in which the combustion gas and the cooling gas are mixed. The cooling duct has cooling gas flow inlets into which the cooling gas flows, a plurality of cooling gas outflow apertures through which the cooling gas having flowed into the cooling gas flow inlets flows out into the mixing duct, and distribution passages through which the cooling gas having flowed into the cooling gas flow inlets is distributed to the plurality of cooling gas outflow apertures.
