Too low a level may expose boiler tubes, which overheats and damages them. Too high a level may interfere with separating moisture from steam, which reduces boiler efficiency and carries moisture into the process or turbine. The drum-level controller maintains the level at constant steam load.

Boiler Operations That Affect Efficiency (Part 1) - BabcockBy reducing the boiler pressure, some of the heat losses through leakages or transmission may be reduced slightly. However there can be problems with the boiler with reduced pressure. The boiler circulation may be upset and the steam lines may have insufficient capacity and flow to transport the low pressure steam.

"Operate the boiler at its maximum design pressure" is a common saying among boiler designers. But too often, this rule is not followed when energy cost reductions are needed. During periods of low steam demand, or when all the use points require pressure-reducing stations, boilers are often operated at substantially less than design pressure.

Boiler Operations That Affect Efficiency. (Excerpted from Steam/its generation and use, 42nd edition) In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production).
