Abstract

Present invention relates to a multiple flame burner which allows activating in a selective manner the totality of burners, a part thereof or at least one ring. Said burner has the ability of placing receptacles of different sizes over said burner, in such a way that if a small receptacle were to be used only one ring would be used, a medium sized receptacle would use a part of said rinse and if a large receptacle were to be used, the entire rings would be used

8. A multiple flame burner according to claim 1, wherein the peripheral combustion ports are divided. into main inner peripheral combustion ports (2191) and main outer peripheral combustion ports (2192) depending on the arrangement thereof, whether it be on the inner crenellated wall (203) or on the outer crenellated wall (204).

9. A multiple flame burner according to claim 1, wherein adjoining the surface (223) of the second Venturi tube (224) a first barrier rail (225) is found comprising a first circumferential groove (226) concentric to the second distribution. channel. (205) in the second section (208) of said inner crenellated wail (203) which is found in fluid communication solely with a pair of main inner peripheral combustion ports (2191) on the sides of said first groove (226), similarly, said first groove (226) presents a wall (2261) which avoids the direct ingress of the combustible-air mixture (10) into said first inner barrier rail (225), said first circumferential groove (226), presents a plurality of radial grooves which come out of said inner segment (203), forming a plurality of first barrier rail combustion ports (227) through. which a part of the combustible-air mixture (10) is ignited once it has lost energy in said first barrier rail;

said first barrier rail (225) which comprises a second circumferential groove (229) concentric to the distribution channel (205) thereby forming a wall (2291) which separates a second. circumferential groove (229) from the distribution channel (205);
