Solution

Advantages of water tube boilers over fire tube boilers :

  • Steam at higher pressures can be produced.
  • Water tube boilers can quickly generate steam at the higher pressure.
  • Higher rate of evaporation.
  • Sediment deposition is less (less tendency of the deposits to settle on the heating surfaces)

Hence, the correct option is (A).

&Key Points:-

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.
