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).
