Abstract

A thermal oxidizer ( 50 ) employing an oxidation mixer ( 51 ), an oxidation chamber ( 52 ), a retention chamber ( 53 ) and a heat dissipater ( 54 ) forming a fluid flow path for thermal oxidation of a waste gas. In operation, the oxidation mixer ( 51 ) facilitates a combustible mixture of the waste gas and an oxidant into an combustible waste gas stream. A heating element ( 55 ) of the oxidation chamber ( 52 ) facilitates a primary combustion reaction of the combustible waste gas stream into an oxygenated waste gas stream. The retention chamber ( 53 ) facilitates a secondary combustion reaction of the oxygenated waste gas stream into oxidized gases. The heat dissipater ( 54 ) atmospherically vents of the oxidized gases. An oxidization controller ( 61 ) may be employed to regulate the operation of the thermal oxidizer ( 50 ), and a data logger ( 63 ) and a data reporter ( 65 ) may be employed for respectively logging and remotely reporting a regulation of the thermal oxidizer ( 50 ) by the oxidation controller ( 61 ).
