In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. High Pressure Water Tube Boiler: The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum.
We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.
