Question

What do you mean by Mountings and Accessories of Boiler? Which according to you is an integral part of the boiler? Explain any three mountings and accessories in details with their specifications and usage.

Answer 1

Boiler mountings are mechanical devices that are considered necessary to operate the boiler smoothly & safely, which are usually mounted on surfaces of the boilers. These are the parts of the system that are mounted on the boiler’s own body for protection of the boiler and for complete control of the steam generation cycle. Machinery protects the boiler from damage to itself due to extremely high pressure, steam backflow, vacuum shell collapse, irregular steam pressure, low water, pumping backflow, and dry running.

Boiler accessories are devices and plants that are installed with boilers to improve the operating condition and overall efficiency of the boiler plant. Boiler accessories are devices that are installed along the boiler and the surrounding area to increase the efficiency of the boiler. These are not an indispensable part of the boiler, and thus without installing these devices, the boiler operation can be completed at low efficiency.

Following are the important boiler mountings:

1. Water level indicator
2. Pressure gauge
3. Safety valve
4. Stop valve
5. Blow off
6. Feed check valve
7. Fusible plug

The essential boiler accessories are:

1. Economizer
2. Air pre-heater
3. Superheater
4. Feed pump
5. Steam Separator
6. Steam trap
