ABSTRACT:
An inexpensive and easily maintained gas burner assembly achieves the manufacturing and maintenance advantages of the conventional sand pan burner design in addition to the heat output and fuel efficiency of more complex burner designs. The invention comprises a tray having a bottom wall and sidewalls defining an interior and an open top. A cover channel having a midsection segment and at least two downwardly depending flanges is adapted to fit in the interior of the tray to form a mixing chamber between the cover channel and the tray. The downwardly depending flanges are spaced away from the sidewalls of the tray to form gaps suitable for filling with a noncombustible granular substance, such as sand or crushed pumice stone. The cover channel additionally comprises at least one projection extending above the top segment and defining at least one burner port. The projection is preferably a longitudinal ridge defining a plurality of burner ports.
