The combustion efficiency calculation considers both the stack temperature and the net heat and moisture losses. This would include losses from dry gas plus losses from the moisture and losses from the production of CO. Combustion converts the carbon in the fuel to CO2. For each type of fuel there is a maximum CO2 that can be converted.

key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.

The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil. 15 - 60% for coal.
