20150337700 | COMBUSTION GAS COOLING APPARATUS, DENITRATION APPARATUS HAVING THE COMBUSTION GAS COOLING APPARATUS, AND COMBUSTION GAS COOLING METHOD - 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. | 11-26-2015 |
20150330274 | COMBUSTION GAS COOLING APPARATUS, DENITRATION APPARATUS INCLUDING THE COMBUSTION GAS COOLING APPARATUS, AND COMBUSTION GAS COOLING METHOD - A fuel gas cooling apparatus includes a cooling duct which causes a cooling gas to flow out into a mixing duct, and a difference of maximum dimensions in a height direction of a flow inlet and a flow outlet with respect to a passage length of the mixing duct is smaller than a difference of maximum dimensions in the height direction of a flow inlet and a flow outlet with respect to a passage length of an expanded duct, or a difference of maximum dimensions in a width direction of the flow inlet and the flow outlet with respect to the passage length of the mixing duct is smaller than a difference of maximum dimensions in the width direction of the flow inlet and the flow outlet with respect to the passage length of the expanded duct. | 11-19-2015 |
