What are Fire Tube Boilers?
Fire tube boilers are a type of boiler in which the heat source, such as flames or fuel gas, passes through the fire tubes in the boiler to heat water and generate steam.
Fuels such as coal, oil, or natural gas are burned in the combustion chamber, and the combustion gas passes through the fire tubes. These fire tubes are tubes filled with water inside the boiler, and they are heated as the combustion gas passes through them. The heat from the fire tubes heats the surrounding water, turning it into steam and increasing the pressure inside the boiler. Utilizing this pressure, the steam is discharged to the outside through the boiler.
The generated steam is used for various purposes such as generating electricity through steam turbines, heating, and processing products. Due to their relatively simple structure and low initial investment cost, fire tube boilers are commonly used in small-scale industrial and commercial applications.
