ABSTRACT:
Material is comletely atomized, and converted into a plasma state by directing the feeding of the burner so that the material to be decomposed and an oxidizing agent (oxygen, air, etc.,) are in a suitable ratio at every point of the equipment so that the waste transforms in stable combustion products. There is no need for a catalyst or for any other subsidiary materials. The recovery of certain end products as chemical basic materials is also effected. The oxidizing agent may be air, air enriched with oxygen or oxygen. Plasma can be produced from air, or from the waste, itself. With waste materials containing halogens, it is advisable to introduce water into the plasma to promote the formation of hydrogen halogenids. A MHD generators or conventional heat exchangers may be used and the final gases are to be desacidified before letting them outdoors by treatng them with a weak alkaline washing solution.
