    Water Tube Boiler - Definition, Components, Working

    The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.

      Why is a water tube boiler more efficient? - Quora

      Water tube boilers have many advantages. The cross section of the water tube boiler tube is smaller than that outside the tube, so the steam flow rate is greatly increased, and the steam generated on the heated surface is immediately washed away, which increases the heat absorption rate of the water.

      Firetube vs Watertube Boilers: a Comparison

      Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy

      How Water Tube Type Steam Boilers Work | Miura Boilers

      As a result, water tube boilers have a much smaller footprint than conventional fire tube boilers, making room for more boilers than can further enhance efficiency. When used in a modular configuration, water tube boilers can be fired up and shut down to keep up with ever-changing steam-output demands, making them much more energy efficient.

      Difference between Fire Tube Boiler and Water Tube Boiler

      Mar 19, 2016 · The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers.
