These mountinng are those fitting which are primarily intended for the safety of boiler and for complete control of the process of Steam Generation.
(1) Water Level Indicator:- It is an apparatus whose function is to indicate the level of water in the boiler.
(2) Fusible Plug:- The function of Fusible Plug is to protect the boiler from being damaged by over heating due to water level falling very low in the boiler
(3) Steam Stop Valve:- The function of the stop valve is to stop or to allow the flow of steam from the boiler to the steam pipe.
(4) Feed Check Valve:- The function of a feed check valve is to control the flow of water from the feed pump to the boiler and to prevent the back flow of water from the boiler to the pump when the pump pressure is less than the boiler pressure or when the feed pump stops working.It is placed at the boiler end of the delivery of the feedpump.
(5) Blow off Cock:- The function of Blow off Cock is to discharge mud and other sediments deposited in the bottom most part of the water space in the boiler, while boiler is in operation. And also to drain-off boiler water.
(6) Safety Valve:- It is a device which comes into operation when the pressure in the boiler exceeds the working pressure.
These are four types:-
(i) Dead Weight Safety Valve.
(ii) Lever Safety Valve.
(iii) Spring Loaded Safety Valve.
(iv) High Steam Safety Valve.
(7) Pressure Gauge:- A Pressure Gauge also called steam gauge is used on boiler to indicate the boiler pressure.
