Abstract

Fuels which on combustion with the stoichiometric air quantity show an adiabatic flame temp. of >=1815 degrees C, are vaporised and passed with air over (1) a solid oxidn. catalyst at 815-1650 degrees C, followed by (2) a non-catalytic zone in wich a further amt. of fuel is oxidised at 815-1650 degrees C. The gas velocity before entering (1) is higher than the max. flame propagation speed and the ratio of free oxygen to fuel in the mixt. is at least 1.1 times the stoichiometric amt. for full combustion. The mixt. is in the ignitable range or on the lean side, and under the oxidn. conditions has a theoretical adiabatic flame temp. of 815-1650 degrees C. The amt. of catalyst in (1) is less than half that required for complete oxidn. of the fuel and the volume of zone (1) is less than that of zone (2). The hot gas from (2) can be used to generate power, e.g. by raising steam, or pref. in a gas turbine. A further catalytic oxidn. stage may be included after (2), pref. between stages of a gas turbine. The gas turbines are suitable for vehicle propulsion, the system producing less CO and hydrocarbon pollutants than internal combustion engines and less NO than conventional gas turbines.
