Fire Tube and Water Tube Boilers

A boiler is a closed vessel in which fluid (generally water) is heated up to high-pressure steam. The boilers are used for the generation of steam. They are mostly used in power plants where steam turbines are used for the generation of electricity. Both fire tube and water tube boilers have advantages and disadvantages in different industrial applications.

Normal efficiency of the fire tube boiler is about 80 to 85 % but this can be increase or decrease by using different a accessories. Efficiency of the water tube boiler is more than that of fire tube and lies within the range of 85 to 90 %. efficiency of water tube boiler can also be increased by using different accessories. The main differences between the fire tube and the water tube boiler are the hot gases flow inside the tube and water surround them in the fire tube boiler whereas, in the water tube, water flows inside the tube and hot gases surround them.

Advantages of Both Systems
You may be wondering which type is better – firetube or watertube? The best way to assess this is to review the advantages and disadvantages of each system:

Firetube Advantages
Smaller in size as compared to a watertube boiler
Fluctuation of steam demand can be met easily
Can be less expensive than watertube boiler
Watertube Advantages
Adding more water tubes can increase the heating capability
The convectional flow in a water tube boiler creates a higher heat transfer rate which can result in higher efficiency
Can achieve very high pressure if needed
