Steam and Hot-Water Space Heating Boilers:Steam

Steam Boiler Low-Water Cutoffs. Steam boilers must be provided with a water-level control device to shut off the automatic fuel-burning equipment when the water level in the boiler drops to a level too low for safe operation.This water- level control device is referred to as a low-water cutoff.The two types of low-water cutoff used on steam boilers are the float type and the probe type.

Steam Boiler Water Level Control

2019-10-1 · Furthermore, the water is mixed with steam bubbles in different sizes. If one opens the valve to a steam consumer then the pressure in the boiler drum falls and hence the steam bubbles expand and the water level rises despite the fact that the water mass actually decreases.

Reasons why the water is bouncing in the gauge

This is a problem you'll sometimes run into with residential steam boilers. If the sections are too narrow, the rising steam bubbles will lift the boiler water level to a point higher than the level in the gauge glass. This happens because there isn't any steam in the water that's in the gauge glass.

Low Water in Boiler - Wet Steam Likely — Heating

The reduction in volume of changing steam to water is a reduction in volume of 1700. The rapid drop in pressure from a positive steam pressure to a vacuum causes some of the water in the boiler to instantly change to steam as the pressure drops and this steam quickly causes water in the boiler to evaporate lowering the water level.
