Abstract:
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.
