Get a QuoteA fire-tube boiler is a type of boiler in which hot gases from a fire pass 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 developed as the third of the four major historical types of
