  • Boiler Operations That Affect Efficiency (Part 1)

    Boiler Operations That Affect Efficiency (Part 1) 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). However, these two goals often have opposing outcomes.Get Price
