Optimal Combustion Process - Fuels and Excess Air

Stable and efficient combustion conditions require correct mixture of fuels and oxygen. The amount of air more than the theoretical requirement is referred to as excess air. Power plant boilers normally run about 10 to 20 percent excess air. Natural gas-fired boilers may run as low as 5 percent excess air. Pulverized coal-fired boilers may run with 20 percent excess air. Gas turbines runs very lean with up to 300 percent excess air.
