How does a fire tube boiler operate?

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.

What is the difference between fire & water tube boiler?

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 and produce steam.

What is the working principle of water tube boiler?

The working principle of water tube boiler is thermal siphoning (circulation of natural water). Basically, this type of boiler includes two drums namely steam, lower or mud drum. The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser.

What is fire tube boiler with example?

Fire Tube Boiler: In this boiler, the hot flue gases are present inside the tubes and water surrounds them. They are low-pressure boilers. The operating pressure is about 25 bar.

Which boiler is water tube boiler?

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 boils water in the steam-generating tubes.

Which boiler is not fire tube boiler?

Cochran; Lancashire; Locomotive; Babcock and Wilcox. (Ans:d). The following are the water tube boilers except. Fire-tube boiler – WikipediaAs these are short tubes of large diameter and the boiler continues to use a relatively low pressure, this is still not considered to be a water-tube boiler.

What are the parts of fire tube boiler?

The fire tube boiler has a furnace, grate, combustion chamber, chimney, fire tubes, and smokebox. The chimney uses to discharge the waste gases and smoke into the atmosphere. They have the capability to uses multiple fuels such as gaseous, coal, liquid/oil, or solid fuels.

What are water tube boilers used for?

Water tube boilers can generate saturated or superheated steam, which is useful for applications such as steam turbine power generation. In addition, these boilers are commonly used in process industries, including chemicals , refining, and pulp and paper manufacturing.

Where are fire tube boiler used?

Fire-tube boilers have the advantage of being easy to install and operate. They are widely used in small installations to heat buildings and to provide power for factory processes. Fire-tube boilers are also used in steam locomotives.
