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.
Learn MoreIn 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.

Learn MoreLow water alarm - For safe boiler operation, the low water alarm ensures that the combustion of fuel does not continue if the water level in the boiler has dropped to, or below a predetermined level. For automatically controlled steam boilers, national standards usually call for two independent low level alarms, to ensure safety.

Learn MoreWater 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.
