Abstract

The utility model discloses a burner, which comprises an oil inlet, an oil nozzle, an air inlet, an air door, a secondary air outlet, a tertiary air outlet, and a casing closing surface. The utility model is characterized in that the air door is a moving structure which can be pushed backwards and forwards; a circular hole-shaped primary air outlet with the diameter of from 4 mm to 12 mm is arranged at a point from 3 mm to 20 mm away from the front of the oil nozzle. The utility model has the advantages that if such a structural burner is used, high pressure oil is not needed to ignite, and mediums are not needed to ignite and burn; the utility model can burn a small amount of oil, a large amount of oil, and inferior oil.

Description

A kind of burner

The utility model relates to a kind of industrial burner.

Existing face formula burner with high oil pressure atomize (〉=0.6MPa), centrifugal blower is combustion-supporting, at the burner internal fires, but can not burn little oil mass oil (less than 15Kg/h), some can burn the import burner service condition harshness of little oil mass, high-pressure blast is arranged, and (blast 〉=0.13MPa) is made atomizing medium, and can only burn 0 ^#Diesel oil.

The purpose of this utility model is to provide a kind of the needs also without the medium ignition, both can burn small quantity of oil with the hydraulic oil igniting, also can burn big gauging, can also burn the burner of poor oil.

The purpose of this utility model is achieved in that

This burner comprises oil-in, fuel injection nozzle, fresh air inlet, air door, the outlet of secondary wind, tertiary air outlet, shell closing in face, it is characterized in that air door be can before and after the movable structure that promotes, wind of garden hole shape that to be provided with a diameter at 3-20mm place, fuel injection nozzle the place ahead be 4-12mm exports.

Adopt a kind of like this burner of structure, do not need also without the medium ignition, both can burn small quantity of oil, can burn big gauging again, can also burn poor oil with the hydraulic oil igniting.

Below in conjunction with drawings and Examples the utility model is illustrated.

Structural representation when Fig. 1 opens for air door;

Structural representation when Fig. 2 closes for air door;

In conjunction with the accompanying drawings:

This burner comprises fuel injection nozzle [1], fresh air inlet [6], air door [5], secondary wind outlet [3], tertiary air outlet [4], oil-in [8], shell closing in face [7], bocca [9], it is characterized in that air door [5] for can before and after the movable structure that promotes, wind of the garden hole shape that it is 8mm that present embodiment is provided with a diameter at the 10mm place, the place ahead of fuel injection nozzle [1] exports [2].

Adopt a kind of like this structure, the switching of air door does not influence air intake one time, when igniting, to push away before the air door, at this moment, the closing in face of air door and shell [7] is fitted, close two, tertiary air, do not allow two, tertiary air disturbs igniting, one time wind then enters in the pipe by fresh air inlet [6], the oil atomization that fuel injection nozzle [1] is sprayed, then from a wind outlet [2] ejection mist of oil and AIR MIXTURES, at this moment just can ignition, so do not need also not need working medium with the hydraulic oil igniting, flame sprays from bocca [9].After the igniting, then with the air door pusher, air door leaves shell closing in face [7], just forms gap [10], the part wind front portion that [10] enter shell from the gap supplies with two, tertiary air, play combustion-supporting effect, when the oil firing amount was little, gap [10] just opened littler, when the oil firing amount is big, just open greatly in gap [10], flame is burnt away, up to completing combustion.

Claims

1, a kind of burner comprises oil-in, fuel injection nozzle, fresh air inlet, air door, the outlet of secondary wind, tertiary air outlet, shell closing in face, it is characterized in that air door be can before and after the movable structure that promotes, wind of garden hole shape that to be provided with a diameter at 3-20mm place, fuel injection nozzle the place ahead be 4-12mm exports.
