【主 講 人】

Terry A. Ring, Professor and Ph.D. supervisor of Chemical Engineering and adjunct Professor in the department of Materials Science and Engineering at the University of Utah.

【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(nèi)容簡介】

在中等或劇烈的低氧燃燒（MILD）中，充分混合的反應(yīng)物需要有一個(gè)體積反應(yīng)場。理 想攪拌反應(yīng)器（PSR）模型是研究在 MILD 條件下熱化學(xué)特性的理想模型。然而，在煤 粉燃燒過程中，很難實(shí)現(xiàn)顆粒周圍反應(yīng)物的充分混合。本報(bào)告根據(jù)傳統(tǒng)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(diǎn)源形式輸送的燃料可能發(fā)生 MILD 燃燒的條件。另外, 實(shí)現(xiàn) MILD 燃燒還要求一個(gè)尺度小于顆粒直徑的混合長度以及一個(gè) 統(tǒng)一的或更小的 DAMKOHER 數(shù)。除此以外, 本報(bào)告還對 MILD 燃燒中碳煙的生成過程 進(jìn)行討論。
