Succeeding to the studies of burning performance of the batch type and the pot type pellet burner. We dealt with the burning performance of a spiral vortex pellet burner. This burner constructed from a outer chamber and a inner chamber a concentric circle chamber.
Accordingly, the burning condition presented a phenomenon of spiral vortex burning in the inner chamber. And the using woody pellet was made of the mixed sawdust and bark.
The burning layer in a burner in turn was consisted of the layers of ash, oxidization, restoration and carbonization up to the upper layer. The burning performance of the burner was influenced by the quantity of blast drived from side and bottom of the burning layer and by the rate of feeding. The optimum condition of the burning performance was the value of 40×10^^^<-2>m^3/s in the rate of air and the value of 16kg/h in the feeding rate. And in this case, the rate of heat was about 55kw.
We concluded that the spiral vortex pellet burner showed great adaptability for the practical use.
