Abstract
A gas-fired burner incorporating an air driven jet pump for mixing air, fuel, and recirculated flue gas is disclosed. The burner is configured for the staged introduction of combustion air to provide a fuel-rich combustion zone and a fuel-lean combustion zone. The burner achieves reduced NO.sub.x emission levels in high temperature applications which use preheated combustion air.
