Your guide to safer boiler operation

Boiler water-level– The first duty when taking over a boiler-room shift is to make certain the pipe, fittings and valves . between the water glass and boiler are free and open by blowing down the water column and water glass and noting the promptness of the return of water to the glass. The most important rule

Steam locomotive - Infogalactic: the planetary knowledge core

During operation, the boiler's water level is constantly monitored, normally via a transparent tube referred to as a sight glass, or with a gauge. Maintaining a proper water level is central to the efficient and safe operation of the boiler. If the water level is too high, steam production is decreased, efficiency is lost and in extreme cases

The float will move up and down as the water level changes in the boiler. The next stage is to monitor this movement and to use it to control either: A feedpump (an on/off level control system) or. A feedwater control valve (a modulating level control system) Because of its buoyancy, the float follows the water level up and down.

up to 45 PSI inlet water pressure. At pressures exceeding 45 PSI, a PRV is required on the inlet cold water line. Operation: Boiler feed pump(s) are controlled by a water level controller mounted on the boiler. If condensate is lost or delayed in the system, it is automatically replaced in the receiver through the make-up water valve.
