Advantages and Limitations of Babcock and Wilcox Boiler

Advantages and application of Babcock and Wilcox boiler

The draught loss of Babcock and Wilcox boiler is minimum
Very high steam generation capacity 20,000 to 40,000 kg/hr
Inspection during operation is possible.
Defective tubes can replace readily.
All portion of Babcock and Wilcox boiler is accessible to inspection, cleaning, and repairing.
Rapid circulation of water can be made.
Very quick steaming. This boiler has ability to raise the temperature of water quickly, so they are suitable were to meet sudden demands.
The water tube and drum are not rigidly connected to the brick wall, which enables the free expansion and contraction during thermal cycle.
It can deliver dry steam of high capacity even under poor feed water supply when compared to other boilers.
The efficiency of 60 to 80%
Less floor area required per unit power when compared to fire tube boiler.

The water used in this boiler must be free from impurity and sedimentary particle. Water treatment is necessary.
Fouling of the tube may cause overheating and bursting of tubes.
Should keep correct water level inside the drum. A failure of water supply for even a short period cause a large problem related to overheating.
