ABSTRACT:
A method of heating a surface susceptible to oxidation or reduction includes generating a central, generally cylindrical, fuel-rich particulate jet, and a coaxial, annular, supersonic velocity, oxidant-rich jet having an auto-thermal ignition temperature greater than the temperature of the fuel-rich particulate jet, directed toward the surface to be heated, the velocity of the fuel-rich particulate jet being less than the velocity of the oxidant-rich jet; allowing the supersonic oxidant-rich jet and the fuel-rich particulate jet to coact to form a coherent particulate fuel-rich and fuel-lean jet having a central particulate fuel-rich region and a coaxial annular fuel-lean region; impinging the coherent particulate fuel-rich and fuel-lean jet upon the surface to be heated for forming a turbulent reaction zone at the surface; and controlling oxidation and reduction reactions at the turbulent reaction zone by adjusting properties of the supersonic oxidant-rich jet and/or the fuel-rich particulate jet.
