The improved incinerator apparatus of the present invention is particularly applicable in the purification of air contaminated with volatilized solvents, and functions through the use of a venturi within the assembly which imposes a low pressure drop while simultaneously obtaining a high degree of turbulence and mixing of the primary fuel with the effluent waste gas being incinerated. The incinerator apparatus of the present invention comprises a solvent vapor conduit for directing a stream of air containing solvent vapors in a first longitudinal direction to be redirected into a venturi. The venturi is preferably disposed within the solvent vapor conduit. A supplemental fuel injector is disposed within the central bore of the venturi to provide gaseous fuel through the central bore to comingle with the solvent vapor containing air for ignition, to provide a sustainable flame for burning the volatilized solvent in the air and thereby to provide air free of such solvent vapors. In preferred embodiments, the sustainable flame also serves to preheat the solvent vapor conduit to provide a preheated stream of solvent containing air for greater efficiency of burning. The net result of the incinerator apparatus of the present invention is to provide sufficient time, temperature and turbulence for removing the volatiles from the air by means of incineration, while simultaneously imposing a low pressure drop upon the apparatus.
