高碱地区预分解窑的工艺实践

Process Operation of NSP Kiln in High Alkali Area

天山股份吐鲁番分公司2002年10月投产的2300t/d熟料生产线,因当地原料碱含量普遍偏高,加上窑炉风量匹配不当等因素作用,致使投产后存在预热器结皮严重、回转窑易结圈结大球、窑系统产量低等系列问题。在分析高碱原燃料及其对系统运行影响的基础上,进行了原料的优化选取和配料方案调整;同时实施了设备的技术改造等配套措施,从而使预分解窑系统得以正常运行,熟料质量基本稳定。

2 300 t/d clinker production line of Turufan Filiale of Tianshan Stock Company was put into production in Oct. 2002. As a result of high-alkali local raw material and improper kiln-furnace air matching and other factors, after put into production, there were a series of problems in the production line like serious coating in preheater, big ringing and lumping in rotary kiln and low output. Analysed the effect of high alkali raw material on system running, the company optimized selection of raw material and adjusted the material proportioning, at the same time, technically restrueted the related equipments, and so made the preheater system run normally and the clinker quality stable.
