ABSTRACT:
A burner for heating a gas stream is disclosed having a primary combustor mounted coaxially within a main combustor to form an assembly. The assembly is coaxially mounted within a burner housing and defines a gas flow space between the assembly and the housing. Gas enters the housing upstream of a substantial portion of the assembly and flows axially over the exterior thereof, picking up heat rejected from the assembly as it travels axially through the housing to an outlet area of a reduced diameter which defines a mixing zone. In the mixing zone, burner output and excess air are introduced to the gas stream in a manner so that the inputs are injected into the exhaust stream in a direction which has a normal component to the direction of gas flow thereby assuring adequate mixing and a resultant even distribution of heat in the flow.
