As further improvement project, uniform 8 ~ 16 coal gas thread passages in the tube wall of annular-jet one end; Described coal gas thread passage is elongated hole, and the ratio of its length and diameter is greater than 6, and one end is communicated with circuit, and the other end links up spout.
As further improvement project, described gas inlet is two.
As further improvement project, the coal gas thread passage of linking up with spout is counter-clockwise helical shape.
As further improvement project, described spout is provided with temperature sensor.
The utility model compared with prior art, has following good effect:
1, by the gas-preheating passage be fitted on outer nozzle wall, preheating is carried out to combustion gas, improve the temperature entering spout and combustion air air mixture like this, make its Thorough combustion, significantly improve the thermal efficiency.
2, uniform 8 ~ 16 coal gas thread passages in the tube wall of annular-jet one end, coal gas to intersect with combustion air with the form of multiple duff air-flow and mixes, sufficient combustion.
3, gas inlet is two, from two position air inlets, can prevent one of them from breaking down on the other hand, affect use of the present utility model on the one hand.
4, the combustion air introduced produces eddy flow through cyclone body guiding after preheating in heat storage, the combustion air of eddy flow is conducive to being mixed in the combustion gas of nozzle, the helical form coal gas thread passage that combustion gas warp and spout are linked up accelerates eddy flow again and sprays, this kind of bispin structure makes combustion air fully mix with combustion gas, burned flame is rotating disk shape, diameter heavy thickness is thin, and this kind of flame combustion is abundant, and the thermal efficiency is high.
