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 10 000t/d production line renovation project and the Saudi YAMAMA 12 500t/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 10 000t/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 12 500t/d production line relocation and technological renovation project has achieved phased results and is expected to be put into operation in 2025.
