Abstract: A plate type heat exchanger for liquid is provided to prevent liquid boiling due to the difference of heat capacities as two kinds of the liquid exchange heat with each other, thereby improving the lifespan and the safety of a system. A plate type heat exchanger for liquid includes path spaces for fluid to be heated and heating fluid. In order to prevent the boiling of the fluid to be heated while a system is stopped operating since the temperature of heating fluid is much higher than that of the fluid to be heated, the path spaces(A1-An) for the fluid to be heated are formed larger than those(B1-Bn) for the heating fluid so as to provide a heat capacity(the boiling point) of the fluid to be heated equally to or larger than that of the heating fluid.

Abstract: PURPOSE: A condensate neutralizer is provided to spray boiler pipe water or blow-down water having high alkalinity to a heat transfer face to prevent the heat transfer face of a condensing heat exchanger from corrosion. CONSTITUTION: A flow limit valve(12) is mounted on a blow-down pipe. A T tube is mounted in front of the limit valve to supply a part of blow-down water to a sprayer(14) through a filter(18) via an electronic valve(11) for pH balancing. An electronic valve(9) for blow-down adopts automatic mode instead of manual one. Thereby, inner pressure of a boiler is transferred to blow-down water by the limit valve to supply the blow-down water to the sprayer in any case. The spraying amount of blow-down water is controlled depending on the opening of the electronic valve for pH balancing. High-temperature high-pressure water in a boiler pipe is cooled through a blow-down water heat exchanger(10) to prevent sudden pressure falling. To spray the boiler pipe water or the blow-down water having regular alkalinity to a spraying nozzle or a pipe, the sprayer adopts a spraying orifice. The boiler pipe water or the blow-down water is sprayed regularly to the heat transfer face of a condensing heat exchanger. Therefore, a condensate having high acidity is washed out and the heat exchanger is prevented from corrosion.
