Croatia: Holcim Croatia has commissioned a new calciner and chlorine bypass system, designed by A TEC. The project converted the kiln from a preheater kiln to a full in-line precalciner by integrating A TEC’s customised calciner solution into the existing process, according to a social media post by the supplier.
A TEC said the new equipment ensures stable material transport, process control and complete combustion with low emissions. The design also accommodates its Post Combustion Chamber (PCC) on the calciner top. The chlorine bypass will apply high efficiency chlorine extraction to maintain control of the chlorine cycle.
