    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

    High Strength Boiler Membrane Water Wall Tube With Ultra

    Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler.

    Why Boiler Designers Use Different Materials in

    Superheaters in boilers have all modes of heat transfer in boiler. They also have a very high length through which the total pick up steam temperature takes places at each unit length. The length of tube and temperature pick-up needed to raise the steam to the required level of super heating calls for using different materials along the total length. These changes in material will have to be
