Detailed description of the invention
A kind of fuel oil oxygen-enriched burner, as it is shown in figure 1, include:
Being positioned at the oil pipe 1 of burner centre, for fuel gallery, one end is connected with oil supply system, and the other end connects with the central small hole 6 of oil-gas mixer 4;
Compressed gas tube 2, for the compression gas passage of atomized fuel, one end is the perpendicular compression gas inlet pipe 9 communicated, and the other end connects with some angling holes 7 of oil-gas mixer 4;
Oil-gas mixer 4, for compressing gas atomized fuel the position mixed, for the cavity body structure that front and back are through, wherein one end is a central small hole and several angling holes being arranged symmetrically with centered by central small hole, the centrage of central small hole and angling hole is acute angle, as shown in Figures 2 and 4;
Reducer tee 3, for oxygen-rich channel, one end is oxygen intake 10, and the other end connects three around oil-gas mixer 4 and the oxygen jet 5 that is arranged symmetrically with, as shown in Figure 3.
Fuel oil horizontally enters into central cavity from oil pipe by the central small hole of oil-gas mixer, compression gas enters central cavity from compressed gas tube by some angling holes of oil-gas mixer, meet around fuel oil and acutangulating in central cavity with fuel oil, collide, fuel oil is sheared, the effect such as stretching carries out one-level atomization and mixes. After fuel oil is compressed gas atomization, burner hearth or combustor is sprayed into from oil-gas mixer cavity outlet with turbulence prediction state, simultaneously, from atomized fuel is broken, the blending further of the oxygen enrichment of three oxygen jet ejections around oil-gas mixer, form two grades of atomizations, and in the burning of distance burner outlet a distance completely, it is to avoid the thermal-flame calcination to burner. Owing to combustion-supporting gas is oxygen enrichment, only compression gas has brought a small amount of noble gas into, therefore combustion flame temperature is high, brightness is big, exhaust gas volumn is few, it is low to take away heat, fuel energy utilization rate is high, and in reaction gas, nitrogen amount is few, NOx etc., and fluff pulp is extremely low, Air?pollution From Combustion is low.
The symmetry of three oxygen jets, around arranging, make oxygen uniformly around atomized fuel, strengthen the oxygen enrichment further atomization to one-level atomized fuel, make the blending of atomized fuel and oxygen enrichment evenly, be beneficial to follow-up abundant burning. Meanwhile, oxygen jet symmetry, one-level atomized fuel is formed " catching " effect around arranging, it is to avoid because one-level is atomized the oil droplet phenomenon thoroughly not caused.
