2016/2/5 · That number is typically 84 to 85 percent. To exceed 85 percent efficiency, the boiler or oil heater can be fitted with an economizer, which is a heat-exchange device in a boiler or thermal fluid heater that improves efficiency and saves fuel. They typically are made of stainless steel and can operate in wet conditions.

Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.
