A boiler with a plate-type heat exchange is provided to improve thermal efficiency thereof and to decrease the volume thereof favorably. In a boiler with a plate-type heat exchanger, a plurality of heat plates(10a,10b) formed with a plurality of flame penetration holes(12,13) formed to pass the flame, and a plurality of water penetration holes(15,16) formed to pass the water are layered. A gasket is installed or welded at the heat plate to pass the flame and the water through the gap between the layered heat plates alternately. The heat exchanger is installed at the inside of the case heat-insulated from the outside. The one flame penetration hole is connected with the burner insertion port formed at the case, directly, and the other flame penetration hole is connected with a furnace through the exhaustion hole perforated at the case. The one water penetration hole is connected with a cold water supply unit through the cold water inlet hole formed at the case, and the other water penetration hole is connected with a hot water pipe through the hot water discharge hole formed at the case, to heat-exchanger the flame with high temperature and the water. |
