  • internally rifled boiler tubes - wikipedia

    Internally rifled boiler tubes - Wikipedia

    Internally rifled boiler tubes are used to evaporate water into steam inside boilers of thermal power plants.Because of their internally rifled shape, they are more efficient. The boiling crisis takes place later, thus allowing for greater heat transfer between the pipe and the fluid inside the pipe. Costs of this type of tube are generally higher than plain tubes.

    Water-tube boiler - Wikipedia

    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
