In a method according to the invention for producing cement clinker, raw ground cement is pre-heated in a pre-heater, the pre-heated raw ground cement is pre-calcined in a calciner, and the pre-calcined raw ground cement is fired in a furnace, wherein fuel and combustion air used in the calciner comprises an oxygen content of at least 75 mol% and the raw ground cement is pre-calcined in a fluidized bed in the calciner. The exhaust gases arising in the furnace are fed to the pre-heater after passing around the calciner and the exhaust gases from the calciner are fed to a CO2 scrubbing device. |
