PURPOSE: To reduce the concentration of soot without increasing the density of NOx contained in the exhaust gas by installing a fuel spray atomizer where a plurality of ejection holes are divided into two groups or more, and the adjoining ejection holes are laid out in positions having different distances from the axial center of said atomizer.
CONSTITUTION: An atomizer comprises a chip main body 1, a back plate 4, and a cap nut 11 of said atomizer. Fuel 2 is distributed mixing ejection holes 10α, 10β and 10γ respectively virtually on an equal basis via a fuel supply hole 9α through a fuel communication pipe 5 where a plurality of opening are board on the back plate 4 of the atomizer. The fuel 4 and an enhanced fine particle medium 3 are collided and mixed with each other in the respective ejection holes 10α, 10β and 10γ, turned into more enhanced fine particles, atomized, and ejected from the atomizer. The flow of fuel thus atomized is mixed with the combustion air, thereby forming flames. Six ejection holes 10α, 10β and 10γ are distributed on a circumference whose radial diameters are different from each other, centering on the axial center of the atomizer. The fuel density in the atomized fuel flow can be shaded while the exhausted NOx density can be reduced by dividing burner flames into two sections.
