IMPROVED GAS BURNER Russian patent published in 2018 - IPC F23D14/06 

FIELD: furnaces and ovens.

SUBSTANCE: invention relates to power engineering. Improved gas burner comprises injector holder (2) fixable to the sheet metal (8) of a cooking hob and provided on its base with injector (10), burner body (14) associated with injector holder (2) and adapted to define with said sheet metal (8) a circumferential passage for the entry of primary air intended to form the combustion mixture with the gas leaving injector (10), at least one cover (28), formed from a single piece of drawn sheet metal, positioned on said burner body (14), and defining therewith at least one radial Venturi effect chamber (36). Said cover comprises circumferential flange (30) provided with a plurality of elongated apertures (32, 40) of essentially vertical extension, for passage of the combustion mixture to generate ring of main flames (34). Surface of said circumferential flange (30) has a vertical inclination. Burner body (14) comprises annular band (22) at its circumferential edge. Annular band (22) of burner body (14) is open and is inclined by an angle corresponding to the inclination of circumferential flange (30) of said cover (28), such as to define line continuity between said cover (28) and the open portion of said body (14).

EFFECT: invention makes the burner cheaper.
