Abstract: A triple ring flame burner composed of a central burner and a toroidal burner that are coupled by a bridge, the central burner comprises a Venturi tube, a mixture chamber, a distribution channel with the toroidal burner composed of a second Venturi tube, a second mixture chamber, a second distribution channel, a stability and flame transfer chamber with a pair of radial walls which divide the distribution channel from the inner crenellated wall to the outer crenellated wall, said radial walls present a plurality of combustion ports that transfer the flame inserted within said radial walls, the inner of the radial walls is in connection with a peripheral crenel for inner stability and transfer and the outer end of the radial walls is in connection with at least one peripheral crenel for outer stability and transfer.

Abstract: There is disclosed a toroidal double ring flame burner comprising a toroidal cover with a lower wall and a burner body comprising a mixing tube which receives and emits a combustible-air pre-mixture; a mixing chamber which receives said pre-mixture and homogenizes it, creating a combustible-air mixture; a distribution channel for distributing the mixture; an inner crenellated wall and an outer crenellated wall, said crenellated walls are separated by the distribution channel and with at least main combustion ports and secondary combustion ports; over the inner crenellated wall, at least one inner barrier rail with combustion ports of inner barrier rail; over the outer crenellated wall, at least one outer barrier rail with combustion ports of outer barrier rail; over the outer crenellated wall at least one outer barrier rail with outer barrier rail combustion ports.

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.
