Advantages and Disadvantages of Benson Boiler

Advantages and Disadvantages of Benson Boiler Points : Advantages and Disadvantages of Benson Boiler Advantages

1. It can be operating mainly economically by varying temperature and pressure at limited loads and overloads. Thu preferred temperature can also be maintained constant at any pressure.
2. Super heater of Benson boiler is integral part of forced circulation system therefore no particular starting arrangement for super heater is necessary.
3. Transfer of parts of boiler is simple as no drums are required and majority of parts are carried to site with no preassembly.
4. As generation of steam is carried out in evaporating tubes at pressure higher than critical pressure it doesn’t need any evaporating drum.
5. It can be put up in a moderately smaller floor area.
6. Benson boiler is lighter in weight by high generation speed of steam.

Disadvantages

1. Evaporation process will leave small deposits during change of water into steam due to which it requires regular cleaning. To obviate this problem, the water softening plant is requiring.
2. The formation of heavy deposits on heating surfaces when impure water is use.
3. Tubes are possible to be overheated in case of water flow is not enough.
4. Boiler control for variable loads is difficult.
