Abstract
Combustion of the carbonaceous fuels such as fuel oil may be carried out advantageously in the presence of an oxidation catalyst body. Under suitable operating conditions the combustion can be effected at high rates of energy release for a catalyst and combustor of a given size, producing an effluent substantially free of pollutants. However, for a given combustor installation it may be desirable at times to utilize a thermal burner, associated with the catalyst arrangement, which is disposed for directing jets of burning gaseous fuel such as natural gas from a multiplicity of points just down-stream of the catalyst. Thus combustion of the gaseous fuel in such jets is obtained substantially throughout a cross section of the downstream zone through which catalyst effluent passes. When a fuel-air mixture is being fed to the catalyst simultaneously with such supplying of gaseous fuel, the thermal burner preferably is arranged to effect coalescing of the jets of burning gaseous fuel and intermixing thereof with substantially all of the effluent from the catalyst. Such intermixing may serve to assist the combustion of any fuel which passes the catalyst without complete combustion during warm-up.
