Abstract
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.
Claims9
A cement production plant comprising:
- a preheater for preheating cement raw meal,
- a calciner for precalcining the preheated cement raw meal,
- a rotary tube furnace for firing the precalcined cement raw meal,
- wherein the calciner has a riser tube line having a calciner nozzle comprising an exterior wall and an interior wall and through which exhaust gases from the rotary tube furnace flow,
- wherein the calciner nozzle is formed by a section of the riser tube line which is constricted into a nozzle form, and
- wherein at least one gas offtake probe which is arranged flush on the interior wall of the calciner nozzle of the riser tube line at a point or plane of smallest cross section of the riser tube line.
