Optimizing Boiler-System Efficiency | HPAC Engineering

A boiler-efficiency improvement of 1 to 2 percent and a steam-distribution-system-efficiency improvement of 2 to 3 percent (in mature facilities) normally can be attained without significant capital expenditures. Therefore, calculating 4 percent of a boiler's annual fuel cost can help determine if action is warranted.

Thermal efficiency - Wikipedia

2020-4-29·In thermodynamics, the thermal efficiency is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, a steam turbine or a steam engine, a boiler, furnace, or a refrigerator for example. For a heat engine, thermal efficiency is the fraction of the energy added by heat (primary energy) that is converted to net work output (secondary energy).
