Problems solved by technology

[0013] In fact, in currently employed propagation channels of constant cross-section (that is, of constant cross-section along a plane transverse to the direction of fluid flow in the channel), the flame, or localized flow of the already combusted fuel mixture, cannot Effectively teleports inside a tunnel to teleport to another fire ring that is not equipped with an ignition device
[0014] Obviously, if the flame is not delivered, one or more of the flame crowns will fail to ignite, causing problems with local leakage of the non-burning fuel mixture and insufficient heat generation by the burner

Embodiment Construction

[0039] The atmospheric burner for gas cooktops according to the invention is equipped with a body 1 on which at least two flame rings 2 and 3 are obtained, which are separated from each other by at least one protrusion of said burner.

[0040] As can be seen in the figures, the flame rings 2 and 3 are substantially concentric and, according to a preferred embodiment, the protrusions are distribution chambers for the gas / mainly air-fuel mixture.

[0041] More specifically, according to a specific aspect of the invention, the burner shown here is equipped with a central distribution chamber 4 combined with a flame ring 2 and a peripheral annular distribution chamber 5 for the fuel mixture combined with a flame ring 3 .

[0042] In other words, the burner according to the invention preferably comprises two flame rings 2 and 3, the first one arranged in a central position and the other in a peripheral position, thus defining two concentric flame crowns.

[0043] It should be noted...

Abstract

An atmospheric burner for gas cookers comprising two or more substantially concentric flame-spreaders, separated from each other by at least one projecting body of the burner, in which each flame- spreader is equipped with a plurality of outlet openings to feed a plurality of flames with a gas / primary air fuel mixture. The burner also comprises at least one flame propagation channel obtained in the projecting body between said at least two flame- spreaders and it is characterized in that the flame propagation channel with which it is equipped include at least a diverging or converging portion.

Description

technical field [0001] The invention relates to a gas burner, preferably for domestic use, of the type comprising at least two flame rings separated from each other by at least one protrusion protruding from the burner, for example comprising a A distribution chamber for the fuel mixture, and one or more passages made in the protrusions to spread the flame between these flame rings. [0002] It is to be noted here and below that the term "flame ring" refers generally, but not exclusively, to an annular element having at least one opening or cutout, hole, etc. Let it ignite and burn. Background technique [0003] Usually, this element is combined with a distribution chamber for the gas / main air-fuel mixture of the burner to form the so-called flame crown (ring of the flame) of the burner. According to known techniques, the flame ring can be produced as a separate part, or alternatively can be produced integrally with the body of the burner. [0004] It is to be noted here ...
