Boiler Efficiency - an overview | ScienceDirect Topics

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.

COMBUSTION

A condensing boiler preserves energy by using heat exchangers designed to remove additional energy from the gases of combustion before leaving the stack. The flue gases produced from condensing boilers are at a much lower temperatures than those of non boilers.

Get acid dew point of flue gas (Journal Article) | OSTI.GOV

In boiler operation, heat loss to flue gases amounts to as much as 20 to 25% of the heat input. To recover heat from flue gases, economizers are generally used to preheat boiler make-up water or forced draft combustion air. The dew point usually limits the practical lower temperature of the flue gas …
