とはない。In order to shorten the length of the flame, it is necessary to promote the mixing of the spray and the ambient air, but since the air ejection hole 6 is provided in front of the stabilizer 2, the spray and the ambient air are further promoted as compared with the conventional case. In order to improve the mixing and the combustion characteristics, the air ejection hole 6 and the secondary air hole 4
Although it is necessary to adjust the amount and flow rate of the combustion air supplied from the swirl vane 3, in this configuration, the air amount and the flow rate can be adjusted by the air holes 12 provided in the blocking plate 11. Therefore, in order to improve the mixing of the spray and the ambient air, even if the air flow velocity from the air ejection hole 6 and the secondary air hole 4 is reduced, the flow velocity around the ignition electrode rod 14 should not be reduced. Can be generated, and the ignitability does not deteriorate.
