• Water-tube boilers have water running through the tubes and fire or gases of combustion surrounding the tubes. The water tubes are connected into a steam drum at the top and a mud drum at the bottom. The fire is in the Combustion chamber. The boiler design can also be identified by the shape of the tube configuration, with the common types being called A, O, and D style boilers. The cast
Water tube boiler. Water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water
