China: KHD Humboldt Wedag has commissioned a Pyrorotor alternative fuels (AF) system on a 5000t/day production line at Conch Group’s Baoshan cement plant in Yunnan Province. The project marks the second installation of the technology in China. During commissioning, the system processed high-moisture biomass and a mix of municipal waste, achieving a feed rate of 18t/hr while maintaining kiln stability. No material build-up at the kiln inlet was recorded, and the unit operated at higher rotational speeds to adapt to challenging fuel conditions.
KHD’s commissioning supervisor A Timuçin Tuzcuoğlu said “The Pyrorotor unit handled the adverse fuel conditions without a problem,” adding that further improvements could be achieved with higher-quality fuels.
Following commissioning, the plant plans to test additional biomass feedstocks, expand AF preparation capacity and explore the use of externally-sourced AF. It also intends to showcase the installation to officials from other plants within Conch Group.
