Abstract
An energy efficient fume incinerator and method for eliminating fumes from a process gas stream while avoiding or minimizing the problem of build-up of organic or other constituents of the fume-laden process gas stream on the surfaces of the heat exchanger in which the fume-laden process gas stream is preheated. The fume incinerator and method are characterized by a first stage reaction chamber for preheating the process gas to a first temperature for preoxidizing organic constituents in the process gas, a second stage reaction chamber for heating the preheated process gas to a second temperature higher than said first temperature for incinerating the fumes; and a first stage heat exchanger for exchanging heat from the process gas exiting from the second stage reaction chamber to the preheated process gas passing from the first stage reaction chamber to the second stage reaction chamber.
