Chat OnlineSuch water tube boilers in thermal power station are also called steam generating units. The older fire-tube boiler design - in which the water surrounds the heat source and the gases from combustion pass through tubes through the water space - is a much weaker structure and is rarely used for pressures above 350 psi (2.4 MPa).
Chat OnlineBoilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
Chat OnlineWater tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam raising and steam generation process is much faster

Ans: Fire Tube: - In fire tube hot flue gases are kept inside the tube and water kept outside the tube .fire tube boiler are small in capacity And in water tube boiler water inside the tube and hot flue gases are outside the tube.
Chat OnlineWatertube boilers contain the water and steam inside a network of mud and steam drums plus the interconnecting bent water tubes. The hot combustion gases used to heat the water circulate outside these tubes. All of this is contained in a large, insulated, and sometimes gas tight enclosure.
Chat OnlineTwo primary types of boilers include Firetube and Watertube boilers. In a Firetube boiler, hot gases of combustion flow through a series of tubes surrounded by water. Alternatively, in a Watertube boiler, water flows in the inside of the tubes and the hot gases from combustion flow around the outside of the tubes.
