Low oxygen and low pressure drop burner

摘要

The improved burner unit of the present invention is designed for use in relatively lower oxygen and/or lower pressure drop environments. The improved burner unit of the present invention comprises a burner base disposed at the bottom of the burner trough. A pair of mixing plates having aeration openings therein are attached on opposite sides of the burner base. The mixing plates include a lower flange for attachment to the burner base and a mixing plate body extending upwardly from such lower flange. The mixing plate body forms the sides of the burner trough and includes an outwardly protruding bulge at the center of the mixing plate. The burner unit also includes side flanges disposed on and extending from the sides of the mixing plate for engagement with like side flanges on like mixing plates to form a burner of the desired length. In preferred embodiments, the bulge in the side of the mixing plate body is generally parabolic in shape as viewed from the trough of the burner.
