1. A double ring toroidal flame burner comprising:
a toroidal cover lid with a lower wall and a burner body comprising: a mixture tube which receives and emits a combustible-air pre-mixture; a mixture 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 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 inner barrier rail combustion ports; over the outer crenellated wall, at least one outer barrier rail with outer barrier rail combustion ports; and a stability and flame transfer chamber with at least one wall which divides the distribution channel from the inner crenellated wall until the outer crenellated wall, the at least one wall of the transfer chamber presents a central section and lateral sections, a first lateral section being in connection with at least one peripheral crenel for inner stability and transfer and a second lateral section being in connection with at least one peripheral crenel for outer stability and transfer; on said at least one peripheral crenel for stability and transfer, inner or outer, a radial combustion port for flame transfer is found. |
