The structure of lower part of the indirect heating boiler is thesame as the regular one. t is composed of the firebox and heattransfer tubes. The upper part is equipped with a heatexchanger. Thereis also an expansion tank at the top Gerierally, theboiler works under normal pressure, so it is absolutely safe.Thethermal media in the boiler is not in or out when the boiler isworking. It transfers the heat between heat transfer tube and heatexchanger. After being heated, the thermal media will oxygenate andintenerate, and there is no furring and oxygen corrosion. These makethe using life of the beller last as 20 years. Build in heat exchanger ismanufactured to comply with manufacturing standard of shell-and-tube heat exchanger Tube pass and shell pass are put to test of waterpressure.
An expansion tank is equipped at the top Water level can becontrolled automatically. It works without pressure, so it is safe andreliable Tedious report-and -endorse procedures are simplifiedBoiler water is only used as thermal carrier, when it is heated, theoxygen will be decomposed and discharged out, so oxygen corrosionwont happen When thermal media water is added once a fewcalcium and magnesuim ions will be heated and be inteneratedBoiler water won't decrease when boiler is working so there is nofurring inside. All these contribute to long life efficiency. Weiningboller's life is about 2 times longer than regular boilers Healexchanger is made of stainless steel lubes which are corrosion-resistant and rust free, offering clean and hygienic hot domestic water.
Indirect heating boiler adopts modular design. Heat exchangerunIts with high performance are used, making the whole structurecompact which make it easy to transport and mount. In the limitedspace, two or more sets can be paralleled in use and the technologyis simpie, so it needn 't heat exchange station and lower the cost ofengIneering.
