本文主要研究内容
作者刘兴,和宇,卢旭超,熊小鹤,谭厚章,惠世恩（2019）在《煤粉热解气化耦合燃烧超低氮燃烧技术进展》一文中研究指出：随着环保政策趋严,常规火电机组经超低氮排放改造对炉膛内部燃烧过程及尾部烟道燃烧后烟气进行氮氧化物协同脱除后,NO_x已达到低于50 mg/m3的水平。随着低NO_x燃烧技术的发展,煤粉热解气化耦合燃烧超低氮燃烧技术已引起重视,其主要思路是在预燃室内引入高温热源,对远低于化学当量比的浓煤粉气流进行加热,煤粉在预燃室内先快速释放挥发分并发生部分燃烧,其气相产物及高温半焦离开预燃室经燃烧器组织送入炉膛后进行低氮燃烧处理。与传统的选择性催化/非催化还原法(SCR/SNCR)等燃烧后降氮策略相比,该技术通过燃烧高温半焦直接在炉内燃烧过程中降氮,技术优势和经济潜力显著。预燃源是产生气相产物、高温半焦的关键环节,笔者根据预燃源方式的不同,介绍了天然气供热煤粉预燃、循环流化床供热煤粉预燃、等离子点火预燃室、感应加热点火预燃室、传统预燃室燃烧器等煤粉预燃技术的发展现状及应用情况,为相关技术人员提供参考。
