A device for regulating the current of air for a multiflow burner with low level of nitrogen oxides (NOx) for thermal generators of electric power plants. The device comprises a tubular register or manifold 15, in the walls of which there are essentially radial through- ports 23 oriented obliquely relative to diametral reference planes. Said register is secured internally and coaxially to the primary conduit 5 of the burner at collecting mouths 14 produced in the latter and through which the primary air for combustion flows in, which air moves through it and converges by a vortex in the primary conduit and reaches the combustion chamber, still in vortex motion, with a flame-stabilising effect. A tubular sluice gate 16 chokes the inflow of air through the register. <IMAGE> |
