A high pressure watertube boiler (also spelled water-tube and water tube) 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-filled tubes that make up the …

28-08-2019· Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high. The water Tube boiler is shown in the figure below.

Water tube boilers are high pressure boiler. 3: Boiler pressure range between 20-25 bar (Low pressure) and for medium pressure boiler pressure range about 25-80 bar. Boiler pressure is up to 80 bar. 4: Fire tube boiler steam production rate is less than water tube boiler. Water tube boiler generates steam 3000kg/Hr Or more. 5

  • Fire-tube boiler: Fire tube boilers are those boilers in which hot gases produced by the combination …There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler. It is a fuel-fired hot water heater. Because of its similarities in many ways to a steam boiler, the term ''hot water …
