Wherein, preferably, described point of firebrick is made up of roof and the sidewall in torus shape, sidewall is provided with multiple fire seperating hole.
Wherein, preferably, described fire seperating hole is counterclockwise helically downwardly towards interior distribution from described sidewall outer.
Wherein, preferably, the quantity of described fire seperating hole is 8, and the even circumferential along described point of firebrick sidewall distributes.
Wherein, preferably, described burner waters building body and is made up of transverse tube and vertical tube, and the junction of described transverse tube and vertical tube is provided with the transition face in chamfering shape, installation and maintenance lid on transition face.
Wherein, preferably, the porch of described transverse tube is also provided with honeycomb ceramics block, and honeycomb ceramics block, described heat storage and described gear firebrick are successively set on described burner by flue gas or air circulation direction and water in the transverse tube of building body.
The beneficial effects of the utility model:
1. heat storage flat flame burner of the present utility model can reduce NO greatly xgeneration, reach better flat flame effect, burning is more fully thus reach energy-conserving and environment-protective.
2. point firebrick in the utility model can control hot air flow to, thus make burner spout flame be the heating that rotation direction state reduces the spout length of flame and is conducive to little space burner hearth workpiece, prevent flame to be directly sprayed onto on workpiece and make workpiece local heat not up to standard.
