  • fire-tube boiler - wikipedia

    Fire-tube boiler - Wikipedia

    A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low

    Firetube vs Watertube Boilers: a Comparison

    Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy

    Are You Keeping Customers' Boiler Tubes Clean

    Over the years, several methods have been developed for cleaning boiler firetubes. Twenty-plus years ago, one popular method was the use of soot blowers: steel tubes fitted with blowing nozzles that were mounted on the tube sheet of the boiler. They were mounted in a way that allowed nozzles to be maneuvered to blow steam or air through each tube.
