Correct Answer - Option 3 : Condenser
Explanation:
Mountings include the fittings which are primarily indicated for the safety of the boiler and complete control of the process of steam generation. The mounting forms an integral part of the boiler and is mounted on the body of the boiler itself. The following mountings are usually installed on the boiler.
- Safety valve
- Water level indicators
- Pressure gauge
- Fusible plug
- Steam stop valve
- Feed check valve
- Blow-of cock
- Man and mudhole
On the other hand, accessories include the components which are installed to increase the efficiency of the steam power plants and help in the powerful working of the boiler unit. These fitting are called boiler accessories. The accessories are given below.
- Air pre-heater
- Economizer
