(57) The invention relates to a cement production system with a preheater for preheating the cement raw meal, a calciner for pre-calcining the preheated cement raw meal, and a rotary kiln for firing the pre-calcined cement raw meal, wherein the calciner has a riser pipe through which exhaust gases from the rotary kiln flow. The gas offtake probe is arranged in a calciner nozzle, which is formed by a nozzle-like constricted section of the riser pipe, wherein the gas offtake probe is arranged flush on the calciner nozzle of the riser pipe.
