Abstract
A method and apparatus for reducing emissions in combustion products. Fuel and primary oxidant are introduced into a burner tube and discharged as a fuel/oxidant mixture, preferably fuel-rich, into a primary combustion chamber. The combustion flame entrains, through a peripheral gap between the burner tube and a wall of a first housing, a first portion of secondary oxidant in the primary combustion chamber. The combustion flame is then directed, preferably through a swaged orifice, into a secondary combustion chamber. Within the secondary combustion chamber, the combustion flame entrains a second portion of secondary oxidant and then combustion products are discharged through an exhaust tube.
