Abstract:
1. A gas humidifier comprising: a heat-exchanger core of a plate-fin type in which a plurality of longitudinal tube plates are laminated in a thickness direction with predetermined intervals so that a plurality of spaces, aligned side by side in the horizontal direction, are formed, with heating-use high-temperature fluid being allowed to flow alternately through those spaces, so as to direct a gas to be humidified to another space from above to below; an injection tube that is inserted virtually horizontally along tube plates on two sides in an upper portion of each space so as to spray a liquid that serves as a steam source into the space in which the gas flows from above to below; and a header pipe that is connected to the injection tube at a place apart from the heat-exchanger core so as to supply the liquid to the injection tube.
