Steam water heat exchanger is an important application of plate heat exchanger in heating, heat exchanger heat needs two kinds of material exchange to complete heat, steam water heat exchanger is the substance A steam heat exchange to B substances in the water, the water temperature of the equipment. For example, the city of central heating, central air conditioning, plumbing, both warm and so on heating needs to have hot water as the heat source, and the heat of the hot water boiler is high, the flow of small, because of slow temperature rise, therefore cannot be used for the heating problem of the city. Power plants and other industrial and mining enterprises and a lot of steam should be excluded, so that the steam water heat exchanger emerge as the times require. The A medium and B medium from steam water heat exchanger.
