摘　　要：弥勒河湾水泥公司2 500 t/d熟料水泥生产线于2010年建成后生产一直不正常,烧成系统产量偏低,窑尾系统塌料频繁,C1筒出口温度偏高。根据现场调研分析,中材装备集团有限公司南京分公司对其窑尾预热器系统采用并实施了NST-I型喷旋结合分解炉技术、半圆半方无集料鹅颈管结构、调整旋风筒内筒尺寸、整流器技术、侧挂式小挂片内筒、月牙形锁风阀、大倾角弧形撒料装置等措施的技术改造。改造后效果显著,熟料产量提高近400 t/d,C1出口温度降低37℃,塌料现象彻底消除。2500 t/d clinker cement production line of Maitreya Bend Cement Company has been not normal since it was built in 2010. The output of firing system was a little low, collapse of preheater system was frequent and outlet temperature of the C 1 cyclone was a little high. According to the site investigation analysis, Nanjing Branch Company, Sinoma Technology ＆ Equipment Group Co., Ltd. re- formed the preheater system, including adopted NST-I type spouting-swirling decomposition furnace technology, half-circle and half-square no aggregate gooseneck structure, rectifier technology, side hung type immersion tube, crescent lock air valve and large angle arc distribution device. After the transforming, the effect is remarkable. The clinker production is raised by nearly 400 t/d, the outlet temperature of C1 cyclone is lowered by 37℃ and material collapse phenomenon is eliminated thoroughly.
