摘　　要：热工烧成技术是水泥生产线大型化、智能化发展的关键。介绍了由天津水泥院自主研发设计的TX-3型弱涡流低阻型旋风筒、第三代自脱硝分解炉、Sinowalk型第四代篦式冷却机等系列先进热工烧成技术装备。以徐州中联10000t/d生产线技改项目及沙特YAMAMA 12500t/d生产线搬迁技改项目为例,介绍了采用先进热工烧成技术装备进行优化改造的技术方案。改造后,徐州中联10000t/d生产线标煤耗降至93kgce/t.cl,熟料综合电耗降低,冷却机热回收效率提高,预热器出口烟气NOX排放浓度≤50mg/Nm3,改造效果较好。沙特YAMAMA 12500t/d生产线搬迁技改项目已取得阶段性成果,预计2025年投产。Pyro technology is the key to the large-scale and intelligent development of cement production lines.This article introduces a series of advanced pyro technology equipment,including TX-3 weak vortex low resistance cyclone,third-generation self-denitrification calciner,Sinowalk fourth generation grate cooler,independently developed and designed by TCDRI.Taking the Xuzhou Zhonglian 10000t/d production line renovation project and the Saudi YAMAMA 12500t/d production line relocation renovation project as examples,this article introduces the technical solutions for optimizing and renovating using advanced pyro technology equipment.After the renovation,the standard coal consumption of Xuzhou Zhonglian 10000t/d production line has been reduced to 93kgce/t.cl,the comprehensive power consumption of clinker has been reduced,the heat recovery efficiency of the cooler has been improved,and the NOX emission concentration of the gas at the outlet of the preheater is≤50mg/Nm3.The renovation has achieved good results.The Saudi YAMAMA 12500t/d production line relocation and technological renovation project has achieved phased results and is expected to be put into operation in 2025.
