Fire tube: where the combustion gases and furnace flame are inside tubes located in a cylindrical vessel that holds the water and steam. Electrical: where electricity is the main energy source to heat the water, eliminating the need for combustion components inside the boiler or flue stacks to vent harmful exhaust.
Fire-tube boiler – Wikipedia. A 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.HVAC Training; This is how a Fire tube Boiler Works In a fire tube steam boiler, heat and gases of combustion pass through the tube surrounded by water.
