Abstract
A thermal treatment system for converting contaminants in soil to non-hazardous compounds. The system includes a combustion chamber in which the soils to be treated are heated to a temperature above the volatilization temperature of the contaminants in the soil. Reagents are injected into the gas stream above the soil which contains the volatized contaminants to interact with the inorganic contaminants to form solid particles that can be collected on a filter for safe disposal. The volatized organic contaminants are burned to form non-toxic combustion gases.
