Abstract
A submersible gas burner includes a pilot burner, a closed gas reservoir, and a first and second main burners. The pilot burner has a pilot burner tube with a closed upper end, an open lower end and a pilot gas inlet adjacent the upper end. The pilot burner provides a downwardly directed pilot flame. The closed gas reservoir has an upper end, a lower end, and a main gas inlet above the lower end. The main burners are coupled to the gas reservoir with upper ends adjacent the pilot burner and opposing lower ends coupled to the gas reservoir. The lower end of the first main burner is further from the lower end of the gas reservoir than the main gas inlet while the lower end of the second main burner is closer to the lower end of the gas reservoir than the main gas inlet.
