Composition.
The know-why of the present invention is: whirlwind groove on the outer wall of inner tube front portion for the air of intake adit, so that air is existed
First mixed combustion room forms rotary air stream；Combustion gas tilts venthole from gas nozzle and sprays, and combustion gas stream is slanted gas flow, rotation
Air stream and the combustion gas stream tilting are mixed into whirlwind mixed airflow, make combustion gas and air mixing more uniform.Mixed airflow is from outer
Pipe front end is mixed combustion outlet and is entered the second mixed combustion room, because mixed combustion outlet diameter is less than in the first mixed combustion room and the second mixed combustion room
Footpath, it is to spray into that mixed airflow enters the second mixed combustion room from the first mixed combustion room, thus mixing further in the second mixed combustion room, works as igniting
Device when flame jet is lighted a fire, the gaseous mixture of combustion gas and air in mixed combustion outlet and the second mixed combustion room burning, combustion gas and air
Gaseous mixture, sprays from flame jet, because flame jet is perpendicular to combustion gas stream side in the second mixed combustion room again after abundant burning
To, thus flame spray direction be along kiln inwall spray, be not directly to spray to kiln center.
Compared with prior art, the method have the advantages that
1st, through the abundant burning of the second combustion chamber, make the burning of combustion gas more thorough, i.e. environmental protection, save again；
2nd, because flame jet is located on the tube wall of conical pipe, spout not directly faces kiln center, makes flame along kiln
Inwall sprays, and enters back in kiln, can avoid flame and be directly sprayed onto on ceramic member or workpiece, cause the mistake of ceramic member or workpiece
Burn；
3rd, combustion gas sprays through gas nozzle inclination venthole, tilts the combustion gas spraying and the air of rotation mixes more fully,
Burning is more abundant；
4th, inner tube is formed by two sections, and by adjusting connection screw thread, adjustable fuel gas nozzle and outer tube front end flame export it
Between distance, thus adjusting the space size of the first combustion chamber；
5th, the flame jet of the second mixed combustion room can be arranged as required to 1～5, is suitable for the different needs of different kilns；
6th, burner structure is simple, easy to manufacture, low cost；
7th, burning is fully reliable, energy-conserving and environment-protective；
8th, kiln internal difference in temperature can be adjusted；
9th, because the direction of bocca flame changes, flame does not directly spray on the product in kiln, makes can make in kiln
Increased with space, can increase by 1/3rd using space, improve kiln utilization rate 30%, energy saving nearly 30%；
10th, the whirlwind universal directional multifunctional bocca of the present invention can be applicable to coal gas, natural gas, liquefied gas, biogas, coal
Oil, heavy oil are the kiln of the energy.For kerosene, heavy oil be the energy kiln when, enter back into the present invention's after kerosene, heavy oil atomizing
Whirlwind universal directional multifunctional bocca.
