Detailed description of the invention

By best embodiment, the utility model is described in detail below .

As Figure 1-3, boiler hydrocarbon alcohol fuel burner, comprises boiler 1, the isobaric work tank 5 of the burner 2 be assemblied in boiler 1 burner hearth, the air utilizing petroleum pipeline 4 to be communicated with burner 2 and fuel; Burner 2 is made up of shell body 8 and the inner housing 7 of admittedly joining within it, and inner housing 7 is bullet, and inner housing 7 bottom extends to the outside bottom shell body 8, forms the vortex air room 9 of annular space between shell body 8 and inner housing 7; Inner housing 7 is made up of with precombustion chamber 12 entirety being positioned at bottom superposed main chamber 10; Main chamber 10 inside has and falls sound lattice 18, and fall sound lattice 18 and arrange from bottom to top in main chamber 10, falling sound lattice 18 is annular solids, and the outward flange falling sound lattice 18 is connected with inner housing 7 inner surface; The taper body wall of main chamber 10 is provided with main chamber wind distributing hole 6, and the wall of precombustion chamber 12 is provided with precombustion chamber wind distributing hole 13; On bottom the precombustion chamber 12 that fuel burner 14 is packed in inner housing 7; Air duct 11 is arranged on shell body 8 side, air duct 11 communicates with vortex air room 9, and air duct 11 connects a bend pipe 17, and bend pipe 17 bottom connects spherical 16, fresh air inlet 15 is arranged at the bottom of spherical 16, and fresh air inlet 15 is bar holes arranged in parallel.Prove through experiment, the utility model air quantity is easy to control, sufficient combustion, and windage is little, the advantage that in combustion process, noise is low.

The utility model in use, fuel is injected air and the isobaric work tank 5 of fuel, compressed air supercharging in air and the isobaric work tank 5 of fuel simultaneously, spray chamber inside is entered into respectively through the forced draught hole of fuel burner 14 and pressure jet hole with the air of pressure and fuel, complete pressure air distribution, fire fuel nozzle 14, fuel is in precombustion chamber 12 and main chamber 10 combustion, precombustion chamber wind distributing hole 13 and main chamber wind distributing hole 6 complete the operation of nature air distribution, realize Thorough combustion; Air constantly enters into spherical 16 by fresh air inlet 15 and produces eddy current, more continuously in vortex air room 9, sends into air by air duct 11.The heat heating boiler heat-exchange device of burning.

The utility model provides boiler hydrocarbon alcohol fuel burner, and it is longer that the boiler solved on existing market has air duct, and intake is wayward, burns insufficient, and windage is comparatively large, the shortcoming that in combustion process, noise is too high.
