An apparatus and method are provided for treating pollutants in a gaseous stream. The apparatus comprises tubular inlets for mixing a gas stream with other oxidative and inert gases for mixture within a reaction chamber. The reaction chamber is heated by heating elements and has orifices through which cool or heated air enters into the central reaction chamber. A process is also provided whereby additional gases are added to the gaseous stream preferably within the temperature range of 650 C-950 C which minimizes or alleviates the production of NOx.
