11/4/2015 · Fire-tube industrial boilers are designed with ratings up to 450 psig and 1500 HP, making them a perfect solution for many small and medium-size facilities. Since the components in a firetube industrial boiler are exposed to heat, combustion byproducts, and boiler feedwater, metallurgy plays a vital role in the reliability of these boiler systems.
3/4/2020 · Compact Boiler. Again, internal furnace fire tube boiler has also two main categories such as horizontal tubular and vertical tubular fire tube boiler. Normally horizontal return fire tube boiler is used in thermal power plant of low capacity. It consists of a horizontal drum into which there are numbers of horizontal tubes.
The boiler is a natural-circulation steam boiler with a water tube structure, producing superheated steam. The boiler is designed for the combustion of both product gas and natural gas. The ceiling of the boiler furnace has four burners, two for each gasifier line. The burners are ignited with natural gas.

fire. (b) Shut off the main power supply for boiler room. Shut off the fuel oil isolating valve. Stop the boiler, and switch off the ventilation fan. (c) Locate the site of fire, and check the cause and nature of fire. Use appropriate fire extinguishers for different type of fires:─ Oil fire : foam, dry powder etc.
The design of fire tube boiler is quite old, as it is one of the most basic types of boiler. Fire tube boilers are also called as smoke tube boilers. Popularly, they are well-known as ‘Shell Boilers’, since all the surfaces in these boilers that contribute heat transfer are enclosed.
Fire tube boilers are useful for small demands of steam and water tube boilers are useful for industrial level usage. To cut short the main purpose of boiler is to boil a liquid mostly the water in order to generate the steam for serving the purpose of heating a building or running an equipment through pressurized steam or pressurized water.
Apr 18, 2019 · Boilers are generally one of three main types – fire-tube boilers, water-tube boilers, and electric boilers. 1. Fire-tube boilers. Fire-tube boilers operate by letting hot combustion gases flow through tubes submerged in water. This converts the water surrounding the tubes to hot water or steam.
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. The...

The main differences between the fire tube and the water tube boiler are the hot gases flow inside the tube and water surround them in the fire tube boiler whereas, In the water tube, water flows inside the tube and Hot gases surround them. Before moving to further detailed explanation lets have some overview of Fire tube and water tube boiler.
Locomotive boiler is a fire tube type boiler. Multi tube is involved in it; all the tubes are horizontally in the horizontally placed drum. It has 116 general fire tube and around 38 super heated fire tube. Furnace that produces heat over the burning of coal is located inside the boiler and hence it is an internally fired boiler.
Due to its shape the boiler is also known as spheroid. The main feature of the boiler is that the furnace of the boiler is surrounded by water and therefore there is no requirement of refractory material. It is a single phase pass boiler, which means that the hot gases pass just through the horizontal tube stack before going to the exhaust.
