China industrial boilers can be divided into two types: firetube boiler and watertube boiler. Our Coal firing tube boilers cost typically less up front than water tube boilers, and offer lower operating costs when compared to a similarly sized industrial watertube boiler. Fire tube boilers operate by sending flue gas through a series of straight tubes surrounded by hot water stored in the same vessel. A wet-back fire tube boiler uses a water cooled turn around zone. Coal fire tube industrial boilers are also easier to maintain due to better fireside access and their efficient straight tube design. Though smaller and more compact in design than water tube boilers of similar size, high quality fire tube boilers can take longer to reach operating temperatures from a cold start and be able to handle steam demand fluctuations well once running. Firetube boilers are compact and low-cost. They are smaller on average than watertube boilers, normally having heat inputs of less than 50 MMBtu/hr. The susceptibility of the firetubes to structural failure places an upper limit on boiler size. Because firetube boilers respond less quickly to load variations, they are used in constant-load applications. Essentially all firetube boilers bum oil or gas.
