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.Get Price

With Flue gas recirculation (FGR), a percentage of the flue gas is reintroduced into the combustion chamber (as part of the combustion air) to cool the core flame temperature to reduce NOx. FGR does require more horsepower to drive larger fans because of both the increase in mass as well as the increased temperature of the combustion air being moved by the fan.Get Price
