The three types of fire tube steam boilers are horizontal return tubular boiler, scotch marine boiler, and vertical fire tube boiler. All fire tube boilers have the same basic operating principles. The heat produced by the gases of combustion pass through the tubes while the water surrounds the tubes. However, fire tube boilers have different
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.
There are two types of steam boilers. One is the fire tube, which is made from one combustion chamber and many tubes. The hot gases that are produced during the combustion process pass from inside the tubes and make a heat transfer with the water that is on the outside of the tubes.
Fire tube boiler with three tube sheets and a turnaround chamber, with a water leg formed between the rear tube sheet an chamber Water tube boilers are designed to work as high as 3206 psi
A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam. Fire tube boiler vs
The design of water tube boilers is strictly opposite to that of fire tube boilers design. In water tube boiler systems, the water to be heated is enclosed inside the boiler tubes whereas the hot combustion gases exhausted by the burner keep circulating around the tube surfaces.Operating Principle: Natural water circulation..
Boiler: A Boiler is a closed vessel in which steams are generated (Water to steam) with the help of coal-burning or other fuel substances.. Basically, There are two types of Boiler. Fire Tube Boiler; Water Tube Boiler; Fire Tube Boiler: The fire-tube boiler is the boiler in which fire (hot flue gases) is inside the tube and water is surrounded by them.. Some example of Fire Tube Boiler are:
Fire-tube boilers sometimes have water-tubes as well, to increase the heating surface.fire tube boilers, water tube boilers- BoilerThere are two main boiler types that you can choose from for your specific application: water tube boilers and fire tube boilers, the two are essentially opposite in difference between fire tube and water tube
In water-tube boilers, the fluid with the higher density flows through the tubes and the fluid of lower density flows through a larger diameter external to the tubes (combustion chamber), ultimately resulting in water-tube boilers having higher overall heat transfer coefficient when compared to a fire-tube condensing boiler of the same size and
However, water tube boilers have a high risk of explosion or bursting compared to fire tube boilers and require more skilled supervision. Treatment of feed water is necessary for water tube boilers as contaminated water can foul the water tubes. The combustion chamber in water tube boiler is located outside the boiler circuit, unlike fire tube
The shell is either 80% full of water - for making steam - or completely filled with water - for generating hot water. They are called fire-tube boilers because the fire travels inside the tubes. Fire-tube boilers have doors that swing open to expose the inside of the fire-tubes for inspection and cleaning.
Fire tube boilers (also known as shell boilers) and water tube boilers are two main types of industrial boilers. Users select fire tube boilers and water tube boilers for specific applications. To purchase an appropriate boiler type is not an easy task because it is hard to say which type of boiler is better.
Fire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives. The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.
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 heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

Fire tube boilers have a series of straight tubes which are situated inside an outer shell filled with water. Water tube boilers have diversely bent and complex tubes which are extended between an upper head namely streams drum and lower heads. The hot combustion gases flow via the tubes heating the water around the tube. Hot combustion gases
Fire tube design use tubes to flow hot gases and distribute it to the safe point of discharge through stack. Water at the outside of tubes is heated by hot tubes, so there is heat transfer between hot gases inside tubes and water outside tubes. Water is converted to steam for process purpose.
The difference between fire tube boiler and water tube boiler can be done on various points. These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler is very crucial.
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. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
A fire-tube boiler is a type of boiler in which hot gases from a fire pass 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. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure
