Abstract

Part of the air current for combustion is guided through a twisting body(6). An underpressure is produced on the downstream section of the flame tube through guides and openings in the flame tube. The exhaust gas from combustion is mixed with the combustion air. The exhaust gas is mixed with the fuel which has vaporised in the combustion chamber but has not yet ignited and a flame front is produced at a distance in front of the burner head. The flame tube comprises a cylindrical section(8) with a further cylindrical section (3) downstream containing the openings (5) and inwardly projecting guides.
