To increase the efficiency of the boiler by optimizing the ...

This is also known as input-output method due to the fact that it needs only the useful output (steam) and the heat input (i.e. fuel) for evaluating the efficiency. Where = boiler efficiency in %. SFR= steam flow rate in kg/hr. SE= steam enthalpy in kCal/kg. FEW= feed water enthalpy in kCal/kg.

Fuel conversion efficiency x-engineer.org

The heating value (also knows as energy value or calorific value) of a fixed quantity of fuel is the amount of heat released during its combustion. The heating value of a fuel is the magnitude of the heat of reaction measured at constant pressure/volume and standard temperature (26 °C) for the complete of a unit of mass of fuel.

Boiler Efficiency and Combustion | Spirax Sarco

Too little air and combustion will be incomplete unburned fuel will be carried over and smokemay be produced. Net calorific value. This is the calorific value of the fuel excluding the energy in the steam discharged to the stackand is the figure generally used to calculate efficiencies. In broad terms:
