PURPOSE:To permit a very efficient incineration by a method wherein a slightly upward whirling current, caused by compressed air, is formed in a combustion chamber while the compressed air is injected into the combustion chamber upwardly from the lower part of the same. CONSTITUTION:A plurality of nozzle tubes are attached to the inner peripheral side of a ring-shaped tube 16a with equal intervals and the whirling current, having a proper thickness, is formed by the compressed air injected slightly upwardly from nozzle ports to make a first air grating layer L1. In the similar manner, an air spply tube 17 also forms a second air grating layer L2. In order to complement the shortage of a supporting force against dropped substances to be incinerated, the compressed air is injected from a double nozzle 10 into the vertical direction. According to this method, the very efficient incineration of the substances to be incinerated, having shapes of powders, grains, fragments or the like, may be effected. |
