EXCESS AIR IN BOILER & Calculation Of Excess Air From O2 % INFORMATIVE VIDEO BOE ||EXAM & INTERVIEW

The percentage of excess air is the amount of air above the stoichiometric requirement for complete combustion. The excess oxygen is the amount of oxygen in the incoming air not used during combustion and is related to percentage excess air. For example, 15% excess air equals 3% oxygen while firing natural gas.
