If steam loads are high, the variable steam flowrate will tend to increase water carryover with the steam, and will tend to make water levels increasingly unstable with the associated danger of low water level lockout, particularly on multi-boiler installations.

Level measurement in steam boilers - Endress+Hauser

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.

If, however, there is a high demand for steam from this boiler, the rate of evaporation will be much greater. This means the control system must add feedwater to the boiler at a much greater flow rate in order to maintain the steam drum water level at setpoint.

1. Priming - This is the ejection of boiler water into the steam take-off and is generally due to one or more of the following: -Operating the boiler with too high a water level. -Operating the boiler below its design pressure; this increases the volume and the velocity of the steam released from the water surface.

STEAM DRUM WATER LEVEL MEASUREMENT

This in turn, means that the level gauge glass will show a lower level than the average water surface level in the boiler shell. The difference between the level in the gauge glass and the level in the boiler shell at high steaming rates, depends on such factors as: The boiler steam generation rating.

STEAM GENERATION IN POWER PLANTS - Water Quality Testing …

In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.
