【導讀】優(yōu)化鍋爐性能的需求和對降低排放的關注，特別是卡夫鍋爐的空氣分布的策略，一直是卡夫鍋爐的升級和演變的驅動力。時間的增加,從而降低大氣排放水平,提高了鍋爐的運行效率。本文提出的一項研究結。果,分析了不同的多級空氣注射，包括各類四次風的配置對煙氣流動模式的交互作用。還進行了只考慮等溫及不可壓縮流動,不考慮熱現(xiàn)象和。研究的數值解證明了仿真結果是與文獻中的數據時相吻合的，硫酸鹽制漿法的光纖工藝線的主要功能是消除木材的木質素。說，它還能使紙漿在最后的漂白工序后達到較高亮度。液的副產品，這種副產品是其木材在蒸煉器蒸煉過程中被提取,并送去回收鍋爐的。黑液有機組成部分的燃燒產生能量，以。這其中，只有一小部分能量經熱電廠轉換成電。目前研究工作的目的是為了提高我們對。燃料型氮氧化物中的氮存在于低溫下燃料釋放并反應后和局部富。生成分析各級噴射氣流和煙氣流動模式之間的相互作所需的數據。
