The screw is used for fixing the central fire cover in the central fire hole jacket on the outer ring fire cover, and then fixing the outer ring fire cover in the base; a central gas inlet pipe on the base, a central gas inlet on the outer ring fire cover and an opening on the central fire cover downwards form a central gas channel; a radial gap between the central fire hole outer sleeve and the central fire cover head forms a central fire hole; the vent hole on the base and the slot with an opening inclined to the bottom of the slot are provided with a central secondary air inlet on the outer ring fire cover, and the central fire cover vent hole on the central fire cover forms a central secondary air channel; an outer ring gas inlet pipe on the base, a groove with an upward opening, an annular groove and a groove with a downward opening on the outer ring fire cover form an outer ring gas channel; a gap between the inner diameter of the base gear ring and the outer diameter of the outer ring fire cover gear ring forms an outer ring fire hole; the vent holes on the base and the outer ring vent holes on the outer ring fire cover form a secondary air channel.
The invention has the advantages that:
1. the fire holes are formed through assembly, so that the processing amount is reduced; the whole structure is transparent, and secondary air is easy to supplement.
2. The product is attractive and elegant, and has bright characteristics and high identification degree.
3. The seamless butt joint with the existing ejector (furnace end) is realized, and the device is very practical.
