非定常プール火炎から排出される燃焼ガスおよびPMに及ぼす初期炉内温度の影響

抄録

In this study, PM exhausted from unsteady pool flame of iso-octane on a shallow dish under various furnace temperature conditions (25 – 700 °C) was investigated as fundamental study of fuel film combustion. Flame appearance during from ignition to combustion end under various furnace temperature conditions was observed. And relationship between maximum flame length and furnace temperature was obtained. Moreover, total masses of CO, CO₂ and PM emitted during flame formation period were measured. As the result, it was also found that total mass of PM exhausted during flame formation period increased with furnace temperature raise.
