燃煤管道排放於大氣中之煙霧光學性質研究

The study of optical properties of the exhaust smoke from chimney in the atmosphere

摘要


利用拉曼和雙波長光達系統,針對化石燃料燃燒所產生的煤灰微粒(氣膠)和水汽進行同步自動化觀測,並對不同微粒之粒徑、光學特性、微粒與水汽作用等進行研究與討論。研究結果顯示微粒與水汽有不同的交互作用,並且微粒成雲機制也可概略從此同步觀測中得以證實。結合光達濃度與粒徑變化等觀測資料,以及不同波長的光對微粒有不同的散射性質,解析出粒子的微物理性質,並討論煙色形成之可能原因。

The aerosols and water vapor produced from fossil fuel combustion are observed by using Raman and dual-wavelength LiDAR systems. The results show that particles and water vapor have different interactions, and the mechanism of particle-cloud formation can be confirmed from this simultaneous observation. The microphysical properties of particles, and the different colors observed from exhaust smoke are also analyzed and discussed from optical theories and LiDAR measurements.
