abstract

Investigations contributing to the development and design of the low emission catalytic reactor to be used in large industrial combustion turbine applications are considered. Experimental results on the behavior of catalytically supported combustion under typical operating conditions are presented. They were obtained by burning No. 2 oil in a flow passage containing an Engelhard catalyst. Temperature measurements are made by specially designed thermocouples along the axial direction of the monolithic substrate. These measurements, at steady-state conditions, include axial variation through the substrate for different conditions of inlet temperature, fuel concentration, and mass flow conditions. In addition, the effect of catalyst length on the temperature profile is illustrated. Emissions measurements are made for the evaluation of the performance of the catalytic reactor under different operating conditions. The conditions required to achieve combustion efficiencies ≥99.5 percent have been experimentally determined. The thermo-mechanical analysis of the support structure of a catalyst element using transpiration cooling has been performed for steady-state conditions. Results show improvements in stress and amount of cooling air required compared to film cooling.
