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.

主权项

1. A heater assembly comprising, in combination:
at least a heater well containing a heater tube module and a burner module, a fuel inlet connected to said heater well for feeding fuel to said burner module, an air inlet connected to said burner module for feeding air to said burner module through a combustion air passage and mixing with said fuel in a fuel-air mixer, an exhaust passage for receiving hot exhaust gases from said burner module, said exhaust passage operatively positioned adjacent and cooperating with said combustion air passage for heating the air in said combustion air passage before said air reaches a burner nozzle, and means for shielding said fuel means from overheating, said combustion air passage and said exhaust passage together defining a single-ended recuperative heat exchange mechanism inside said heater well.
