High temperature rough gas mix with the combustion air sprayed into from combustion air nozzle, spray in high temperature rough gas rotation function and combustion air
In the presence of entering kinetic energy, after-combustion is sufficiently mixed, flame sprays burner body.The surrounding air that surrounding air nozzle sprays is on the one hand
Burner body exit site is cooled, and prevents high-temperature flue gas from destruction is produced to which；On the other hand, surrounding air causes flame to keep
Good rigidity, prevents flame patch wall and solid fuel particle from separating from air-flow, while a certain amount of secondary wind of supply, has
Beneficial to the carrying out of combustion process.
Used as further improving and supplementing to above-mentioned technical proposal, this utility model takes following technical measures：
Along the axial arranged multiple rows of combustion air nozzle of burner body, the axis of combustion air nozzle and burner body which is located
The angle ɑ of the RADIAL of position is 0～45 ゜, preferably 0～15 ゜, and the combustion air that Jing combustion airs nozzle sprays is in burner body
Portion forms the circle of contact.
When raw gas enters burner body with cyclonic form, its direction of rotation is consistent with the direction of rotation of the circle of contact.
Often arranging combustion air nozzle has 2-4 along the circumferentially uniform nozzle of burner body.
The center of the combustion air nozzle is burner body inner passage diameter D apart from L with burner body outlet
0.1～1.5 times, preferred 0.2-1.0 times.
Described surrounding air nozzle is nozzle ring, positioned at the outside of burner body outlet, along burner body outer ring
Arrangement.
The out conductor of the gas entry be connected with inside cord by way of transition line or with gas exit circumference on
Certain point be attached, the region formed by the two comprising gas exit cross section.
This utility model has the advantage that as follows：Coal dust can reach more than 99% burnout rate, coal gasification processes
In, the nitrogen-containing compound major part in coal is reduced to the nitrogen of simple substance, can reduce the discharge of about 50% nitrogen oxides；
Using the coal burner of this kind of after-combustion of first gasifying, energy-conservation, the purpose for reducing discharging can be significantly reached.
