技术介绍
周边烧嘴式气体燃料石灰竖窑(以下简称气烧窑)由于能够利用低热值纯高炉煤气,窑的一次性炉龄较回转窑、套筒窑、并流蓄热双膛窑要长,设备运转率高、运行费用低、吨产品投资小等优势,仍是钢铁工业生产冶金石灰的主要窑型之一。气烧窑的工作原理是把具有一定块度的石灰石从窑的顶部加入,由于重力的作用,物料自上而下移动,煅烧好的石灰由窑底出灰机卸出,燃料气及其燃烧所需要的空气(一次助燃风)从窑的中部喷入窑内,竖窑中物料与气体相向流动,物料自上落下,气体自下而上,所以它是一个逆流式的热交换装置。气烧窑建筑高度在35m左右,有效高度在22m左右,内径2~4m,在窑体中下部共设有上下两排烧嘴,每排各安装有10个沿窑体周边均匀布置的套筒式烧嘴,同排相邻两烧嘴间的夹角为36°,上下排相邻两烧嘴间错角18°。燃料气和一次助燃空气从窑体周边煤气环管和空气环管中经均匀布置的20个套筒式烧嘴喷入窑内,燃料气和助燃空气进入窑内进行混合、燃烧后生成的高温火焰对石灰石进行焙烧分解。新砌筑或长时间停产冷却后的气烧窑开炉点火时需将大量的软、硬木柴和少量废柴油、废棉纱等引火材料搬运至位于上排烧嘴上方的点火平台处;在窑内投入6~8吨焦炭至窑底出灰机风帽以上200~300mm(保护出灰机),然后装石灰石15~20吨;再从点火平台处的煅烧带人孔加入软木柴100~150kg,硬木柴500~700kg,再加入软木柴50~100kg和少量废棉纱;在垫好的底柴上浇20~25kg废柴油,将点着的火把从人孔投入炉内,待火旺后再人工投入硬木柴 ...
