Fire-tube boiler - Wikiped

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.. The fire-tube boiler developed as the third of the four major historical types of boilers: low ...

It is just the opposite of the fire tube steam boiler; the water is in the inside of the tubes and the hot gases are on the outside of the tubes. In the fire tube boiler, we have a limitation on the combustion chamber diameter and length, and it cannot exceed a certain value. So for large-scale industry, generally the water tube boilers are used.

In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.

Introduction Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from 250 to 50 000 kg/h (175 to 34 000 kW). Operating Principle Steam is generated by heating a large volume of water in a pressurised drum by means of hot gases, which are produced from the combustion of liquid or ...

This meant that the boiler had a heat absorption rate of 3,347 Btu per hour per square foot of heating surface. The equipment used for these tests was the “state of the art” for the time (late 1800’s). Thereafter, it became the industry practice to rate boilers in boiler horsepower and to base this rating on heating surface, e.g. 1 Bhp per 10

IB&M’s boiler retubing process includes: Inspection - IB&M visually inspects each boiler, and perform NDT testing as needed. We use dye penetrant testing to expose areas of boiler tube sheet cracking. Boiler Tube Extraction - old boiler tubes are removed along with the tube ends. Any minor tube sheet cracks are then repaired to the ASME code specifications.
