(57) A bypass system is used in the system and method for producing cement clinker, wherein a portion of a furnace exhaust gas occurring in a furnace is channeled off as a bypass gas via a bypass line connected between the furnace and a calciner, cooled and dedusted. The dedusted bypass gas is then directed back to the calciner and/or into a tertiary air duct arranged between the cooling means and the calciner and/or into a region between the furnace and the calciner.
