Abstract

An improved flame retention head assembly for use in the air tube of a fuel burner having a fuel nozzle in the tube. The assembly includes a tubular member having in sequence a conical, cylindrical, and flared section with air-fuel mixing means in the conical section, and air passage means in the cylindrical and flared sections. The size of the air passage means in the cylindrical section can be adjusted. This device with its air level combinations, allows an excess of combustion air of 5 to 15% only, thus resetting in flame temperatures of more than 3,000.degree. F.
