On June 10, the Sichuan Yadong and Jiangxi Yadong projects jointly undertaken by AVIC International Beijing Company and Germany Humboldt (KHD) were successfully ignited:
the contracted kiln shutdown and docking period of Sichuan Yadong 3 # preheater energy-saving and resistance-reducing transformation project was 80 days, and the actual construction period was 77 days.
Jiangxi Yadong 2 # Preheater Resistance Reduction and Energy-saving Renovation Project has a contract period of 80 days for kiln shutdown and docking, and an actual construction period of 80 days. The original plant of
Sichuan Yadong Cement Co., Ltd. was designed by Humboldt, Germany, and this energy-saving and resistance-reducing transformation was jointly constructed by AVIC International Beijing Company and Humboldt (KHD), Germany, to optimize the steel structure of the kiln tail tower and upgrade the preheater. The new LowNox preheater calciner system designed by KHD of Germany is adopted.
Jiangxi Yadong Cement Co., Ltd.'s Original preheater, rotary kiln, kiln hood, tertiary air duct, burner and other firing core systems are all designed by German Humboldt (KHD). This energy-saving and resistance-reducing transformation adopts the LowNox preheater calciner system designed by German Humboldt (KHD). The steel structure of the kiln tail tower frame and the pulverized coal pipeline system are optimized and reformed. After the
transformation, the comprehensive coal consumption of clinker per unit product, clinker output, C1 outlet negative pressure and C1 outlet temperature of the two plants have been greatly optimized and improved.
