20100204495 | HYDROCARBON/OXYGEN INDUSTRIAL GAS MIXER WITH WATER MIST - A hydrocarbon-containing gas is mixed with an oxygen-containing gas in a gas mixer in the presence of a water mist. The water mist surrounds and contacts entrained particles in either the oxygen-containing gas stream or the hydrocarbon-containing gas stream.
