2019-4-24 · 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).

Each of these sources offer its own method for calculating the boiler's heat input rate. A separate method, however, works for all boilers. The boiler's heat input rate is proportional to the rate at which the temperature of the water within it rises. The factor relating these rates is the specific heat …
