Which is the fire-tube boiler?

A fire-tube boiler is a type of boiler in which hot gases from a fire pass 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 are the parts of fire-tube boiler?

Different Components & Mountings Placed on the fire tube boiler

• Safety valve.
• Feed check valve (a kind of non-return valve)
• Water level indicator.
• Pressure gauge.
• Steam stop valve.

What are fire tube boilers used for?

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.

How many tubes does a fire-tube boiler need?

Fire tube boiler typically have three or four passes, although one and two pass boilers are also in use.

How does a firetube boiler work?

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) 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.

Is fire tube boiler internally fired?

Internally Fired Boilers: The boilers in which the furnace is located inside the boiler shell are called internally fired boilers. Among all the fire tube boilers, most of the boilers are internally fired boilers.

What is the operation of a steam boiler?

The operation of a steam boiler is equally simple. The heating element is brought to a high temperature. The tank water eventually will begin boiling and creating steam. As steam builds, it is held in the empty part of the tank known as the dome, creating a highly pressurized environment.

What is a fire tube and water tube boiler?

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.
