Industrial type watertube boilers are seldom selected for low-pressure heating plants except for large building complexes. The main reasons are the high cost of this type of boiler as compared to the cast-iron or steel firetube boiler
suijitupian41.jpg" />: The watertube boiler is employed for high-pressure, high-temperature, high-capacity steam applications, e.g. providing steam for main propulsion turbines or cargo pump turbines. Firetube boilers are used for auxiliary purposes to provide smaller quantities of low-pressure steam on diesel engine powered ships.

suijitupian87.jpg" />Boiler Types and Classifications. 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.
suijitupian165.jpg" />High Pressure Boiler is mostly water tube boiler in which water is on the tube side while flue gas flows through the tube, hence transferring heat from flue gas to water with cross flow heat transfer. A steam boiler is a high pressure boiler when it operates with the steam pressure above 6MPa. The high pressure boiler is widely used for power generation in thermal power plant.
suijitupian48.jpg" />A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler.
