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 second deployment of the system in China. During commissioning, the Pyrorotor system processed high-moisture biomass and a mix of municipal solid waste, achieving a feed rate of 18t/hr while maintaining kiln stability. The kiln operated at higher rotational speeds to adapt to challenging fuel conditions, with no material build-up recorded at the inlet.

KHD Humboldt Wedag’s commissioning supervisor 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 Baoshan plant team plans to test additional biomass feedstocks, expand fuels preparation capacity and explore the use of externally-sourced AF. The plant will also showcase the installation to representatives of other plants within Conch Group.
