1. (PG60.1) All boilers having a fixed water level (steam and water interface) shall have at least one gage glass (a transparent device that permits visual determination of the water level). 2. (PG‐60.1.1) Boilers having a maximum allowable working pressure

Water Levels in Steam Boilers | Spirax Sarco

Water Levels in Steam Boilers The task of any steam boiler is to provide the correct amount of high quality steam: safely, efficiently, and at the correct pressure. Steam is generated by heat from the combustion of fuel in a furnace, or by waste heat from a process.

Sight glass - Wikipedia

Sight glass. Water gauge on a steam locomotive. Here the water is at the "top nut", the maximum working level. Note the patterned backplate to help reading and toughened glass shroud. A sight glass or water gauge is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid

2016/2/24 · This is undesirable not only because the steam is excessively wet as it leaves the boiler, but it contains boiler water with a high level of dissolved and perhaps suspended solids. These solids will contaminate control valves, heat exchangers and steam traps, impacting the performance and operation of the system.

Methods of Detecting Water Level in Steam Boilers | Spirax Sarco

High water alarm - The alarm operates if the water level rises too high, informing the boiler operator to shut off the feedwater supply. Although not usually mandatory, the use of high level alarms is sensible as they reduce the chance of water carryover and waterhammer in the steam distribution system.
