Abstract
The invention discloses a cooker burner. A first induction tunnel, a second induction tunnel and a third induction tunnel on an injector are fixedly and correspondingly connected and communicated witha first gas passage, a second gas passage and a third gas passage respectively. The gas for an inner ring tooth cap enters the second gas passage from the second induction tunnel. The gas for an outer ring tooth cap enters the first gas passage and the third gas passage from the first induction tunnel and the third induction tunnel. As a result, the gas can be fully mixed with the air when entering from the injector. Three fire-holes are formed on the outer ring tooth cap. The first fire-hole is positioned on the inside elevation of the outer ring tooth cap. The third fire-hole is positionedon the upper end face of the outer ring tooth cap. The second fire-hole is positioned on the upper end face of the outer ring tooth cap between the first fire-hole and the third fire-hole. The secondfire-hole and the third fire-hold are inclined to the center of the outer ring tooth cap and the inclination angle of the second fire-hole is larger than that of the third fire-hole. Therefore, the flame heat on the fire-hole is more concentrated to the bottom of a boiler and the generation of carbon monoxide and compounds of nitrogen and oxygen is reduced. A fire block ring is fixedly sleeved onthe outer surface of the outer ring tooth cap so as to reduce the loss of burner heat.
