摘要介绍了MFC分解炉+五级单系列旋风预热器系统的改造方案，该方案采用了自还原脱硝技术，调整了三次风管接入位置和C4旋风筒下料管位置，使用了重锤压紧式窑尾密封，采用了无外风节能型强旋流入炉燃烧装置。技术改造后，系统阻力降低，年均电耗下降1.62kW·h/t熟料，标煤耗下降3.15kg/t熟料，满足了氮氧化物排放值＜100mg/m³（标）的要求。

Abstract: In this paper, the transformational scheme of MFC decomposition furnace & 5-stage single series cyclone preheater system is introduced. The scheme adopts self-reducing denitrification technology and adjusts the access position of 3rd-air pipes and the feeding position of C4 cyclone tube. In addition, this scheme also adopts the heavy hammer compression kiln tail seal, and the energy-saving strong swirly flow into the furnace combustion device without external air. After the transformation, due to the lower resistance of system, the average power consumption is reduced by 1.62kW·h/t.cl, the standard-coal consumption reduced by 3.15kg/t.cl, and the NOx emission value controlled less than 100mg/Nm³, which meets the emission requirement.

Key words: ultra-low emissions system resistance reduction capacity expansion and velocity reduction of calciner denitrification and NOx emission reduction
