By adding heat to boiling water, indirectly via a combustion tube and burner, as in a conventional boiler. By reducing the pressure on water stored at its saturation temperature. This results in an excess of energy in the water, which causes a proportion of the water to change into steam.

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.

Boilers are essentially shell-and-tube heat exchangers, with water being boiled to steam or transformed to high pressure hot water. Heat is generated by burning a fossil fuel; the combustion gas can be ducted around tubes containing the water (water-tube boiler), or the hot gas can pass inside the tubes with the water being in the shell (fire

2 days ago · A boiler heats water or another liquid under pressure in an enclosed space to create steam or hot liquid. There are a variety of boilers available in both the commercial and residential markets, classified by the system of heating the liquid, the types of fuel they use, and even the axis of the boiler (horizontal or vertical).

Direct system hot water storage system with small hot water only boiler Here, the water is heated by a hot water only boiler. These can either be a small gas fired boiler called a 'circulator' designed to heat the water directly or the water can be heated by a small back boiler situated behind a solid fuel fire.

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 …
