Abstract
A flat burner is provided, for household appliances, having a burner body (2) with an axial gas delivery passage (4) housing a gas injector and with a cap (8) resting on the body (2) through an annular ring (9) having flame orifices (12), an annular transversal convergent-divergent system being defined by the annular surface (11) of the body (2) bordering the passage (4) and the opposite surface (10) of the cap, in which: the diameter (D.sub.E) of the passage (4) is D.sub.E =D.sub.c .multidot.K.sub.3 with K.sub.3 =1.10 to 1.43 and D.sub.c =the diameter equivalent to that of the venturi of the convergent-divergent D.sub.c =D.sub.i .multidot.K.sub.4 with K.sub.4 =12.5 to 22 and D.sub.i =diameter of the injector for butane gas; the angle (.alpha.) of the convergent-divergent system is between 3.degree. and 8.degree.); the length of the divergent system is ##EQU1## with D.sub.1 the outer diameter of the ring; and mechanical means are provided for setting the diameter D.sub.c as a function of the gas used.
