Calculation of the Excess Air of Combustion Proces

Therefore, when the boiler is below full load, the amount of excess air required increases to ensure a complete combustion. In coal-fired boilers for example, at 50% load, takes two times excess air than when the load is . Although the excess air is important to ensure complete combustion, excess air has a negative impact on boiler efficiency.
