ADVANCED THERMAL CONDUCTIVE HEATER SYSTEM FOR ENVIRONMENTAL REMEDIATION AND THE DESTRUCTION OF POLLUTANTS

摘要

A thermal conductive heating and desorption system is disclosed, which provides superior results to other systems for the removal of pollutants from soil, groundwater and other affected medias using a novel enhanced gas fired recuperative heater and oxidation system. Pollutants in the affected, heated media are partially destroyed by hydrolysis, pyrolysis and/or oxidation processes. Remaining pollutants are extracted from the affected media, and pollutant off gas is then introduced into the heater system where it is both thermally and catalytically oxidized. Heat from combusted fuel and pollutant off gas in the heater system is used to preheat incoming combustion air through a recuperative heat exchanger, enabling significant reductions in fuel usage by the heater system. Combusted fuel and off gas discharged from the heater system may be further treated to achieve specified discharge standards.
