Understanding Boiler Safety Controls - Technical Articles

Low Water Level Controls . Low or no water in the boiler can lead to severe damage. When the water level drops below the minimum level, the boiler's high temperature affects metallurgy's strength. If temperature soars to a high enough value, it can even melt the steel. A control system continuously monitors the water level to avoid problems

Steam generator (boiler) - Wikipedia

2020-9-4 · A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler.[1] The narrow-tube construction, without any large-diameter drums or

What to do if your boiler loses pressure - British Gas

The position set when the boiler was installed is sometimes shown by a red indicator needle. On most digital gauges, you'll see a flashing pressure reading, if there's a low (or high) pressure warning. If your boiler pressure reads less than 1 bar, it's possible that you might have lost water from the system, which needs to be replaced.

Mcdonnell & Miller Low Water Cutoffs - Taco Low

A low water cutoff is a device that detects when the fluid level in hot water and steam boilers drops below the minimum safe operating level specified by the boiler manufacturer. If this should occur, the low water cutoff will cut-off the burner and shut down the boiler. If a boiler is "dry-fired" (burned without water in it), it can result in boiler failure, or a possible fire/explosion.

What is a Low-Water Cutoff? - Definition from

A low-water cutoff is a mechanical device (usually a float switch) that is used to turn off the burner or shut off fuel to a boiler to prevent it from running once the water drops below a certain point. If a boiler is "dry-fired" (burned without water in it) it can suffer rupture or catastrophic failure.
