冷凝間接加熱熱水鍋爐的下半部結構與普通鍋爐一樣，由燃燒室與傳熱管組成;上半部分裝有熱交換器，爐體上部裝設有膨脹水箱，由于鍋爐整體是在常壓狀態下，故絕對安全。尾部煙道加裝冷凝器，提高熱效。爐內的熱媒水，在鍋爐運行的全過程中，不進、不出，與熱交換器之間傳遞熱量。換熱器嚴格按照管殼式換熱器制造標

準制造，殼程和管程分別作水壓試驗。

爐體上部設有膨脹水箱，水位自動控制，無壓運行，安全可靠，簡化了繁雜的報批手續。爐水只作熱載體使用，在運行時，水中的氧加熱析出，排出爐外，爐內長期使用不會發生氧腐蝕，一次性加入熱媒水，有限少量的鈣鎂離子亦被加熱軟化，運行時爐水不增不減，因此鍋爐內部不發生結垢，延長了鍋爐使用壽命，是一般

鍋爐壽命2倍以上。

間接加熱熱水鍋爐模塊化設計，高性能換熱組件，機組結構緊湊，使產品易于運輸、安裝，在小空間內，多臺機組可并聯使用，其工藝系統也很簡潔，免去了換熱站的設計與施工，工程費用省。   

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.
