摘要

2097588 9210215 PCTABS00013 A soil remediation unit (10) includes a counterflow drum (22) for burning off volatile hydrocarbons and delivery to a cooler drum (28). Particulate-laden gases of combustion flow through a separator (36) wherein the particle stream is delivered to a cooler drum and the gas stream flows to a thermal oxidizer (52), the exhaust gas from which lies in heat exchange relation with the gas from the separator. Portions of the exhaust gas are passed into the separator in counterflow relation to the particles for remediating the particles.
