Figure 5-6 is a simplified block flow diagram of the KoBra project. Raw brown coal is dried to 12% moisture by the newly developed WTA process which is a fluidized bed with steam and integrated waste heat recovery. Air for the gasification is extracted from the combustion turbine. The gasifier is sized at about 3,600 t/d of dry brown coal to match the 200 MW Siemens V 94.3 combustion turbine. The bottom ash and fly ash from the gasifier is combusted in a separate atmospheric pressure circulating fluidized-bed combustion (CFBC) boiler.
