<p>A device and method for oxidizing gaseous materials, the device comprising a combustion chamber (230), a flue gas outlet (216) operating in conjunction with means for applying negative pressure to the outlet, means for introducing process gas and a fuel (214, 220) into the top (222) of the combustion chamber (230) means for effecting heat exchange (234) between oxygen-containing gas and the combustion chamber (230) to preheat the oxygen-containing gas, means for introducing the preheated gas into the top (222) of the combustion chamber (230), and means for mixing the preheated gas with the process gas and fuel (256) so that the mixture can burn in the combustion chamber (230) to form a flue gas. The heat exchanger (234) may concentrically surround the combustion chamber (230). The preheated oxygen containing gas may swirl in a first direction as it enters the combustion chamber (230) and be mixed with process gas and fuel swirling in the opposite direction. Particulates may be removed (250) from the combustion chamber (230).</p> |
