“…Catalytic combustion of natural gas has been attracting attention since the mid-1970s when natural gas came to be used worldwide, and various kinds of application concepts have been proposed [1,2]. Premixed catalytic combustion can indeed guarantee the lowest NO x emissions compared to other combustion technologies, as detailed in Fig.…”

“…As another tendency, as mentioned in the paper of Sadamori [9], NG cannot burn more easily than hydrogen at low temperature either. In the revised combustor without a swirl device, the natural gas, that is, in the conditions of case 2, was not burned in the simulation.…”

The asymmetric inner structure of a catalytic combustor causes wall cracking because of regional overheating. Thus, a symmetric shape is proposed in the present work and analyses of the computational fluid dynamics of the existing combustor and the proposed type have been performed. A simulation of the revised combustor without a swirl device revealed that the flow of gases is concentrated on the center of the combustor and only catalysts around the center are used. In the revised combustor with a swirl device, the overall temperatures were estimated to be uniform. However, near the swirl device, high temperature exceeding 1,700 K was measured. Therefore, a heatproof surface coating on the swirl device is necessary for protection of the material. At the initial start-up of the catalytic combustor, hydrogen and natural gas are used. When only natural gas is used, the simulation indicated that the gas does not burn in the revised combustor without a swirl device. However, in the combustor with the swirl device, methane of 34.8% volume burns in the simulation. On the other hand, when hydrogen and natural gas are burned together, methane of 91.7% volume burns in the simulation.
