These are the devices that are installed with a boiler and its neighboring area to increase the efficiency of the boiler. These are not the essential part of the boiler and therefore without the installation of these devices, the operation of the boiler can be achieved despite a lower efficiency.
Boiler assemblies are the components of the assembled machine on the boiler body for the safety of the boiler and for complete control of the steam generation process.
Several boiler assemblies are as below:
1) Manometer
2) Water level indicator
3) Fuse plug
