| Research Abstract |
When the required inlet temperature of a gasturbine is around 1400ﾟC,the flame-less buming by using the catalytically stabilized combustor. Since the working tmperature of the reactor does not exceed th minimum flame temperature, a low NOx reaction can be achieved. However, thermal durability of catatlyzer arrest the development of such a high temperature catalytic combustor. One of the breakthrough for a problem of thermal durability may be a use of CST combustor. The exhaust gas from a catalytic combustor is re-heated up to the required temperature by combustion of the additional fuel in the thermal reactor following after the catalytic reactor. The present research was carried out to develop a mixing method without flame initiation. The maximum temperattLre of the catalyzer must be kept below 100ﾟC for the present heat resistivity. In order to arrest an unnecessary temperature rise at any local zone in the reactor, it is necessary for a secondary mixture to be rapidly mixed with the hot exhaust from catalytic combustor so as to avoid a flame initiation at the nozzle port under a blow-off or a blow-out condition. The experimental results at th elevated pressure from latm to 4atm, showed that over a certain level of pressure, a flame-less mixing, and a stable combustion are possible even in a relatively smau volume of the reactor. Thus a temperature rise with a low NOx combustion is achieved by the low temperature thermal reaction of fuels.
