The retrofit of JD-Heideberg JY plant has been successfully put into operation

As a sub-project of the SCR denitrification technical retrofit project for Line 2 at BBMG-Heidelberg Jingyang Plant, the technical revamp of the first-stage cyclone has been successfully commissioned for four months. The pressure drop across the cyclone body has been reduced by over 500 Pa, while the dust concentration at the outlet has dropped significantly, laying a solid foundation for stable operation of the subsequent SCR system.

Following the scheduled commissioning of the SCR system in December 2024, the total incremental pressure drop of the clinker burning system will be controlled within 100–200 Pa compared with pre-retrofit conditions (net pressure change: -500 Pa from cyclone optimization plus ~700 Pa from the SCR unit). This effectively curbs the rise in power consumption for clinker production induced by the SCR denitrification system.

In addition, reduced heat loss carried by fly ash delivers a moderate cut in the thermal consumption of the burning system.

During the implementation of this sub-project, our team continuously deepened cooperation with BBMG-Heidelberg Cement. Both sides jointly discussed technical countermeasures and conducted multiple rounds of in-depth demonstration and operating condition simulation on the details of the process scheme. While fully ensuring all performance indicators meet standards, we minimized the project capital investment and reduced additional structural loads of equipment.

The stable commissioning of the Line 2 kiln SCR denitrification project strongly supports BBMG Heidelberg Cement in achieving its annual energy conservation and emission reduction targets. It also lays a solid foundation for the stable operation of ultra-low emissions of the production line throughout 2025 via optimized thermal systems.
