The oil fire tube condensing boiler is a kind of safe and high efficiency heating equipment with full automatic control system. The oil fired condensing boiler is fast assembly fire tube boiler with three pass structure, it has compact structure, small volume, strong load adaptability and low water quality requirement.
We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt
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. The other type is a water tube steam boiler.
The boiler consists of a shell, a tube sheet on each end of the shell, and tubes connecting the two tube sheets. The boiler is mounted above a steel or masonry furnace. The products of combustion leave the furnace and are directed through the tubes at one end of the boiler. After passing through the tubes, the products of combustion exit the opposite end of the boiler and are directed to the stack or chimney.
A fire-tube boiler exploded at the Grover Shoe Factory in Brockton, Massachusetts, on March 20, 1905, which resulted in the deaths of 58 people and injured 150. Then on December 6, 1906, a boiler in the factory of the P.J. Harney Shoe Company exploded in Lynn, Massachusetts .
1. Fire tube or Water tube- Fire tube boilers are those boilers in which smoke/Flue gas travels inside the tubes and in the water tube boilers, the water flows inside the boiler tubes. 2. Internally or Externally fired- For boilers using burners are internally fired, while those using coal are externally fired. Generally on ships, we use internally fired boilers.
Jul 02, 2016 · In fire tube boiler, the fuel is burnt inside a furnace. The hot gases produced in the furnace then passes through the fire tubes. The fire tubes are immersed in water inside the main vessels of the boiler. The heat energy of the gasses is transferred to the water surrounds them.

The firetube boiler design (see Figures 1-1 & 1-2) uses tubes to direct the hot gases from the combustion process through the boiler to a safe point of discharge. The tubes are submerged in the boiler water and transfer the heat from the hot gases into the water. inside a firetube boiler the hot gases travel down the furnace
Boiler Selection - Fire Tube vs. Water Tube. A large firetube is designed for 5 sqft per horsepower "because of perception in the domestic market", for no other reason, nobody in the rest of the world builds firetubes with 5 sqft per HP heating surface. You'll find some European designs that have as little as 3.5 sqft.
Jul 07, 2019 · Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water. The examples of the fire tube boiler are the simple vertical, Cochran, Lancashire, Cornish, Locomotive, Scotch marine, and Velcon boiler.
Material for Fire Tube. These fire tubes are conected to a burner at one end, which delivers a 2.5m long flame with 750mm in diam, 1.6E6 Kcal/h and which has 2000°C at its hotest point (inside feather). For protecting the fire tubes from the flame there is another inside tube (length= 3m) made of Incoloy or Inconel.

The construction code for the fire tube boiler is ASME Code Section I, and it covers the minimum requirements for design, materials, fabrication, inspection, testing, and preparation for initial delivery. For more detailed information about fire tube boiler shop inspection, review the following articles: Third Party Inspection for Fire Tube Boiler
The fire-tube boilers covered a steam production range of 1-20 t/hr at pressures from 10 to 20 bar. Fuels include heavy fuel oil (HFO), Sasol gas, paraffin and coal. The survey covers a total of 85 fire-tube boilers inspected over a four year period (1998-2001).
Scale insulates the heating surfaces reducing the ability of the fire tubes to transfer heat from the hot combustion to the boiler water. High stack temperatures or ruptured tubes are common problems related to scale build up. Boiler water also contains dissolved gases such as oxygen or carbon dioxide.
Aug 22, 2018 · Actually in fire tube boiler one closed vessel or shell contains water, through which hot tubes are passed. These fire tubes or hot gas tubes heated up the water and convert the water into steam and the steam remains in same vessel.
The main two basic boilers are: Water tube boiler. Fire tube boiler.
A fire-tube boiler is a cylindrical high mass pressure vessel where hot flue gases pass through many small diameter tubes set within a tank of water. These hot gases transfer the heat through the walls of the tubes into the water.
For this type boiler heat passes through the boiler drum or tube. For this reason, Heating Surface of Fire Tube Boiler is less than Water Tube Boiler. Fire Tube Boiler generates less steam than Water Tube Boiler. Some experiment found that a Fire Tube Boiler can generate 18000 pounds (8164 Kg) steam per hour.

Simple vertical fire tube boiler produces steam with low pressure and in small quantities. It uses for low power generation or for limited space.
Fire tube-design boiler systems are very typical for this service, where the heat from the fuel passes through the inside of the tubes, and water contained in a pressurized vessel surrounding the tubes is heated and converted to steam. 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.
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. Water tube boiler have higher rate of steam production compare to fire
fire-tube boiler designs specifically for particular jurisdictional requirements, again with acceptable reliability and efficiency. Manufacturers of other boiler types, such as vertical, water-tube and cast iron sectional boilers, have used the Bhp output rating as a means of comparison with fire-tube boilers.
