Fire-tube boiler - Wikipedia

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or 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-pressure tank or "haystack"

removal of sample tubes for DWD analysis, and based on the DWD results may be chemically cleaned. Meanwhile, the boiler water chemistry must be strictly controlled, as a delay of one or two years on a fouled boiler can result in major tube damage. The type of boiler (recovery vs. power) and how it is used also affect the cleaning strategy.
