SL NODisadvantage
1.Complex design and High maintenance cost.
2.A skilled operator is required for operation.
3.This is used in large power plants and it is uneconomical for use in small industries.
4.For the same power output, the cost of a water tube boiler is high.
5.Treatment of feed water is very essential in a water tube boiler as small-scale deposits inside the tube can cause overheating and bursting.
