After the heat transfer of the flue gas of the fire tube steam boiler through the smoke chamber into the human tube (the first return smoke tube), the smoke temperature is low to the front smoke box (generally around: 450℃), making the structure of the front smoke box simple, generally with steel structure lined with […]

The efficiency of the wet back fire tube boiler can reach more than 95%, and the thermal efficiency can reach 98% after installing the condensing device. Wet back steam boilers adopts integral design, high efficiency, good heat exchange, fast heating. Boiler can use full premixed surface technology and flue gas external circulation (FGR) technology, to […]
