ABSTRACT:
An apparatus having an incineration chamber and at least one burner for oxidizing fumes is provided. First and second regenerators are in fluid communication with the incineration chamber, as is a bypass which introduces unburnt fumes to the incineration chamber without passing them through either of the regenerators. While the fumes are in the bypass, a purging device, including a purge fan and accompanying conduits and valves, introduces a purge gas to either one of the regenerators to force unburnt fumes therefrom. The purged fumes and the purge gas are mixed with the incoming fumes from the bypass in an annular plenum downstream of the purged regenerator before they are introduced to the incineration chamber for oxidation. The flow of incoming fumes to the system may be continuous, even during purging, and the purge fan may also be continuously operated.
