  • Boiler Level Control - IMI Critical Engineering

    2019-9-10 · A certain area of water surface is required in a boiler from which to release the steam. Clearly, as steam is generated, the water in the boiler evaporates, and the boiler must receive a supply of water to maintain the level. This requires water to be maintained at the correct level. Safety is also of paramount importance.
