A device for oxidizing gaseous materials, comprising a combustion chamber, wherein the device and the combustion chamber both have a top and a bottom, the device further having a gas outlet and being adapted to operate in conjunction with means applying negative pressure to the outlet, means for introducing process gas and a source of fuel into the top of the combustion chamber, means for effecting heat exchange between oxygen-containing gas and the combustion chamber to preheat the oxygen-containing gas, means for introducing the preheated gas into the top of the combustion chamber, means for mixing the preheated gas with the process gas and fuel so that the mixture can burn in the combustion chamber to form an exhaust gas, means for permitting the gas to exit from the bottom of the combustion chamber, means for diluting the exhaust with air to form a flue gas, and means for directing the flue gas from the bottom of the combustion chamber out of the outlet of the device. The heat exchanger may concentrically surround the combustion chamber, and the preheated oxygen-carrying gas may swirl in a first direction as it enters the combustion chamber, there to be mixed with process gas and fuel swirling in the opposite direction. Means may be provided for removing particulate materials from the combustion chamber. Also disclosed is a method for incinerating materials in a gas stream using the disclosed incinerator.
