A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low …Get Price
The term boiler is applied to the single heat source that can supply either steam or hot water (a boiler is often called a heater). Boilers may be classified according to several kinds of characteristics. They are typically made from cast iron or steel. Their construction design may be sectional, portable, fire-tube, water-tube, or special.Get Price

In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more compacts. But they are more likely to explosion, water volume is large and due to poor circulation they cannot meet quickly the change in steam demand. For the same output the outer Get Price
Apr 12, 2020 · A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.Get Price
The Water-tube boiler consists of the furnace. Water flows through these tubes. Coal and air are burned in the furnace. The heat from the combustion heats the tube as well as the water inside the tube. Remember in the case of a fire tube boiler, the tube doesn't have water, it has hot gases instead of water.
