Fire Tube Boiler - Construction, Types and Its Working
Fire tube steam boilers produce low pressure steam. There are three main types of fire tube steam boilers: Cochran, locomotive, and Lancashire. A fire tube steam boiler can be fitted with an economizer to enhance its efficiency and heat recovery system.
Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as 'fire tube' or 'smoke tube' boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler …
Main Features. Key features of fire tube boiler systems include: "Fire tube boilers are often characterized by their number of passes, referring to the number of times the combustion (or flue) gases flow the length of the pressure vessel as they transfer heat …
The low-pressure range of fire tube is up to 20 bar whereas in water tube up to 250 bar. The load fluctuations in the fire tube cannot be handled whereas, in a water tube, it can be handled easily. This boiler occupies more floor area for output whereas, in a water tube boiler, it occupies less area.

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …
2020/10/17 · The following disadvantages of fire tube boiler are: The fluctuation of load cannot be easily handled. The rate of steam generation is low. A Fire boiler is used in small power plants. The maximum working pressure is up to 20 bar which is a less comparatively water tube boiler…
It normally extracts steam from the low-pressure turbine. High Pressure Heater (HP): A Feedwater Heater located downstream of the boiler feed pump. Typically, the tube-side design pressure is at least 100 Bar, and the steam source is the high-pressure turbine.
2014/8/26 · The difference between the two is that the Water tube boilers are safer and last much longer than the fire tube boiler. Their size is also larger and have a faster recovery time. However fire tube boilers have a low cost.

HS Code : 84021910- - Steam or other vapour generating boilers (other than central heating hot water boilers capable also of production low pressure steam): Superheated water boilers - Fire tube horizontal (lancanshire) boilers export customs shipment data
ME 416/516 Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water.
These boilers are generally extra really fired. The boiler pressure limited to 20 bar. The boiler pressure is limited to up to 100 bar. The fire-tube boiler has a lower rate of steam production. A higher rate of steam production. Not suitable for larger power plants.
