A hybrid catalytic combustion can provide low NO_x emissions with gaseous and distillate fuels while maintaining catalyst bed temperature about 1000℃ for extended catalyst life. The combustor consisted of a preheater, a premixed fuel injector, a catalytic reactor, a homogeneous combustion and dilution zone. Studies were carried out using a 30mm diameter combustor and a 100mm diameter combustor. Fuel was CH4 gas. Operations were performed at 0.1 to 0.7 Mpa pressure and about 10-30m/s reference velocities. At homogeneous combustion gas temperature about 1200-1500℃, combustion efficiency was greater than 99 percent. Thermal NO_x emissions Were measured below 10 ppm. The effect of pressure on NO_x Was less. These results show that a hybrid catalytic combustion can be applied to gas-turbine equipment.
