Abstract

An inner cylinder of the utility model adopts a fully nested structure, and a wall adhering spiral flow, a forwards rushing spiral flow, a radial jetting flow, a core winding axis flow, a wall adhering axis flow, etc. can be formed in the inner cylinder through the artful arrangement of an oblique air intake groove, a tangential air intake groove, an axial air intake opening and a radial direction air intake opening. Therefore, the temperature of a casing, particularly the temperature near a cover at the bottom end of the casing, is reduced, so that the service life of the utility model is prolonged, the working environment is improved, the stay time of flames in the inner cylinder can be prolonged and the temperature and the stability of the flames can be favorably improved. Therefore, the problems of coking, charcoal deposit, etc. during burning heavy oil can be better solved. The utility model can be used for burning residual oil, emulsifiable oil, etc.

Below will use accompanying drawing elaborates to the utility model.

Accompanying drawing 1 is that the utility model only uses the structural representation of joint during sleeve.

Accompanying drawing 2 is vertical views of the base plate 35 of tube 31 at the bottom of the utility model.

Among the figure, 1 housing, 2 inlet scoops, 3 inner cores, 11 upper end covers, 12 bottom covers, 13 separate seats, 14 oil nozzle seat, 15 fire holes, 31 end tubes, 32 sleeves, 33 final stage sleeves, 34,36 heat insulation baffle liners, 31B, 31C, 32A, 32B, 33A, 36A, tangential admission groove, 16 17 33B, oblique air inlet duct, 18 31A, 31D, 32C radial air inlet hole, 311 321 oared segrne pii, 19 axial admission holes.

As seen from the figure, the outstanding feature of inner core 3 of the present utility model is the structures that adopted an a kind of complete set folded, because the effect of sleeve and heat insulation baffle liner is arranged, add because whole inner core 3 leaves housing bottom cover 12 segment distance is arranged, this just makes near the temperature the temperature of housing, especially its bottom cover be able to remarkable reduction, and the benefit of bringing thus is also can prolong in be improved life-span of burner of working environment; The utility model also is comparatively careful in the consideration of prescription gas face, the air that enters from inlet scoop 2, a part enters inner core 3 via the axial admission hole 19 on the base plate 35 of end tube 31 and forms axial flow wind around oil nozzle, a part is via the oblique air inlet duct 16 on the base plate 35,17 enter inner core 3 forms adherent air-flow, and it is relatively large via on each section of inner core perisporium, notch is tangential admission groove 31B longitudinally, 31C, 32B ... enter the range of atomization, the combustion zone also forms the preshoot swirling eddy, outer wall by the intussusception part exists adherent axial flow or swirling eddy again, add through radial air inlet hole 31A, 31D, 32C ... the radial jet that enters, to use the traction air-flow that enters through oblique air inlet duct 33B, make fuel quite abundant with mixing of combustion air, and also corresponding prolongation of the time of staying of flame in inner core, flame temperature increases, in addition, the coking when also having solved burning heavy oil simultaneously of rotatablely moving of air-flow and flame, carbon-collecting problem, flame temperature also evenly and flame stabilization do not wag the tail.
