While the efficiency of the boiler is the work performance or the level of performance of the boiler or steam boiler obtained from a comparison between the energy transferred to or absorbed by the working fluid in the kettle with the input of chemical energy from the fuel. For the level of efficiency in boilers or steam boilers, the efficiency ranges from 70% to 90%.

Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure. Does not include any evaluation of any complex boiler configurations or fluctuations in operation.
