Performance Test and Efficiency of Boiler | Thermodynamics

The samples for analysis should be taken at the boiler exit, at the entries and exits of the auxiliary plant (i.e. economizer and/or air heater) if fitted; and certainly at the nearest predictable point to the fuel bed. It is usually assumed that if the CO 2, CO, and O 2 quantities are measured and the balance to 100 percent taken as nitrogen, then the analysis is complete.

Boiler Efficiency and Combustion | Spirax Sarco

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.
