  • Patent number: 10288354
    Abstract: A high-efficiency plate type heat exchanger increases a heat-exchanging efficiency with an exhaust gas by connecting unit fluidized beds formed with stacked heat exchanging plates to each other in up and down directions, and elongating a flow path of circulating water to be greater than or equal to two passes (2-PASS). The heat exchanger retrieves heat of an exhaust gas by increasing a flow amount of circulating water of a portion close to a burner while a circulation path is elongated as described above. In addition, the high-efficiency plate type heat exchanger increases efficiency thereof by inserting a baffle plate having distribution holes between unit fluidized beds, controlling a flow of an exhaust gas while reducing an exhaust speed of the exhaust gas using heat exchanging fins of the baffle plate, absorbing heat of the exhaust gas, and effectively using a heat transfer area.
