【主講人簡介】
Dr. Ring's research includes colloidal particle processing, precipitation, crystallization inhibition, thin film sensors and ceramics processing. He was a member of a DOE/OIT team that produced a CFD model of crystallization systems. He has published one book on Ceramic Powder Processing, >165 articles on particle processing and has 4 patents and 8 patent applications. His recent work is on high-speed imaging, image analysis and laser diagnostics of flames and optical analysis of soot and ash particles produced in flames as well as their deposits.
【內容簡介】
在中等或劇烈的低氧燃燒（MILD）中，充分混合的反應物需要有一個體積反應場。理 想攪拌反應器（PSR）模型是研究在 MILD 條件下熱化學特性的理想模型。然而，在煤 粉燃燒過程中，很難實現顆粒周圍反應物的充分混合。本報告根據傳統氣體燃料 MILD 燃燒的要求，利用 PSR 模型清楚地確定以分布式點源形式輸送的燃料可能發生 MILD 燃燒的條件。另外, 實現 MILD 燃燒還要求一個尺度小于顆粒直徑的混合長度以及一個 統一的或更小的 DAMKOHER 數。除此以外, 本報告還對 MILD 燃燒中碳煙的生成過程 進行討論。
