The cylindrical part of the spray dryer (0) had a height of 00 m and a diameter of 0.0 m. The internal fluidized bed (IFB) had a diameter of 0 m and a weir height of 0.00 m. The drying gas was fed via a gas distributor (0) at the top of the spray dryer. The drying gas was partly recycled (drying gas loop) via a baghouse filter (0) and a condenser column (00).
