Abstract

The fan fitted burner has feed systems for air, liq. or gaseous fuel, a flame tube protruding into the combustion chamber, and a return pipe for part of the flue gas to the air feed system. - The region of the return pipe (20), which is at a temp. above the flue gas dew point, when the burner (13) is in use, has an inlet (22) for the ambient air.
