ABSTRACT:
A gas burner of the type in which a inflammable mixture is caused to flow out of a diffuser, is formed of a plurality of parallel slots separated by grid elements, and distributed into a pair of grids separated by an elongate screen extending between the two grids. The burner includes at least one elongate slot extending perpendicular to said screen along the width of said grid pair, perpendicular to the screen, near the grids, and adapted to take up relative dimensional variations of said screen and the grid elements brought about by differential heatings of the screen and the burner walls surrounding the diffuser.
