オイルバーナを用いた火炉内の燃焼シミュレーション

抄録

Combusting flow simulations in an oil furnace (0.1MW) were carried out in order to investigate droplet behavior and the flame-holding mechanism. Measurements made by a phase Doppler anemometer were also examined to elucidate the followability characteristics in recirculation flow, The results show that a droplet under 30 microns can follow the flow but a droplet over 50 microns penetrates. The use of connective flux of O₂ and CO₂ both in the flame and the entire furnace was examined and the results demonstrated that it was very useful to show the self-recirculating flow in furnaces.
