A fire-tube boiler differs from a water tube boiler, and 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 table below gives a brief comparison of Water Tube and Smoke Tube Boilers-comparison of water tube and smoke tube boilers
There are two main types of boiler in use, these are the Fire Tube Boiler and the Water Tube Boiler. Fire-Tube / Smoke Tube In this type of boiler the combustion of fuel occurs within a confined space and the hot exhaust gases pass through the inside of steel tubes, which are surrounded by water. Water-Tube Type
Fire-tube boiler - Wikipedia. The earliest form of fire-tube boiler was Richard Trevithick's "high-pressure" Cornish boiler. This is a long horizontal cylinder with a single large flue containing the fire. The fire itself was on an iron grating placed across this flue, with a shallow ashpan beneath to collect the non-combustible residue.
2019-9-29 · Normal efficiency of the fire tube boiler is about 80 to 85 % but this can be increase or decrease by using different a accessories.

May 05, 2017 · Water tube boilers work in a similar style to fire tube boilers. They also have tubes, a water source, and a radiation source. In the water tube boiler, tubes are arranged in the heater in almost all potential ways to generate maximum heat. The only exception in the way the sources are adequately hooked up.
Fire tube VS water tube gas boiler Compared to firetube designed boiler, the watertube gas boilers are safer by design, and it can operate many years longer than firetube boilers. Unlike the firetube gas boiler, a gas fired watertube boilers are available in larger capacities and recover faster than.
Aug 30, 2019 · What is a Fire Tube Boiler. In Fire Tube Boilers, hot flue gases will be flown inside the tube and these tubes are surrounded by water. These are the low-pressure boiler which cannot generate much heat compared to water tube boilers. As the production of heat is less the overall efficiency of this boiler is also low. The figure which depicts

Sep 03, 2019 · Fire tube boiler vs Water tube boiler. Boiler is a closed vessel used to produce steam. Industrial boilers mainly can be classified as a fire tube and water tube boilers. The difference between fire tube boiler and water tube boiler depends on many factors.
The water in the tubes creates steam directly, instead of tubes heating water as is the case in a fire tube boiler. Water tube boilers are used more for industrial applications and less for heating purposes. A fire tube boiler transfers heat through tubes via thermal conduction, which then heats the water in the container and formulates steam. In other words, the boiler is the pressure vessel that contains the water. Difference between fire tube boiler and water tube boiler. a.
ZG Group supplies gas and oil fired boiler, fire tube and water tube from 1 ton to 130 ton. The boilers can be used in steam, hot water and electricity applications in many industries where need them. No matter fire tube gas and oil boiler or water tube gas and oil boilers, both of the two boilers have their own advantages and disadvantages.
Fire tube boiler can be used in small industry. 4. Treatment of feed water is not very essential in fire tube boiler. 5. No pure feed water is required in FTB, So cost can be minimized because pure feed water is costly. 6. For the same power output, the cost of a fire tube boiler is less as compared to a water tube boiler.
Fire tube boilers are a lower cost alternative to water tube boilers and are often used for smaller industrial facilities with lower operating pressures. The main advantages of a fire tube boiler are its simple construction, compact size and the ability to easily meet rapid fluctuations in steam demand.
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. Here are a few key differences between the two:
In Fire-tube boilers hot flue gases pass through tubes and water surrounds them. In Water-tube boilers water passes through tubes and hot flue gasses surround them. 2 These are operated at low pressures up to 20 bar.

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.
Fire tube boilers are low pressure or medium pressure boiler. Water tube boilers are high pressure boiler. 3 Boiler pressure range between 20-25 bar (Low pressure) and for medium pressure boiler pressure range about 25-80 bar.
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.
In order to increase the boiler capacity, the fire-tube boilers will eventually have to increase the volume of the water jacket, whereas water-tube boilers simply have to increase the surface area of the water tubes by either increasing the number of tubes or passes.
