The high-temperature flue gas that media water produces with fuel gas buring under vacuum environment carry out that heat exchange produces steam and under vacuum environment the water of steam and required heating carry out heat exchange generation condensed water, condensed water carries out heat exchange with high-temperature flue gas again and produces steam, and the water of having avoided required heating that recycles of media water directly contacts high-temperature flue gas generation incrustation scale.

The beneficial effect of vacuum steam generating heat exchanger for wall-hung condensing gas furnace of the present invention: vacuum steam generating heat exchanger for wall-hung condensing gas furnace passes through to absorb the smoke pipe waste heat simultaneously by cycle applications, heating in vacuum to treated media water, realize heated media water vapor, do not need to carry out again any water treatment, reduce the corrosion that heating water brings because of acid treatment to the circulatory system, with heat exchanger because of the adverse consequences such as heat exchange efficiency reduction that incrustation scale causes, avoided adverse consequences such as burning because of water tank that fouling causes.
