An integrated apparatus for the production of clinker starting from raw meal is described, comprising a rotary kiln (3); a multistage cyclone preheater (1) connected downstream of said rotary kiln (3) with respect to the direction of flow of the fumes (10) of a combustion taking place in said kiln (3); possibly a precalciner (2); a catalytic system of removal of NOx (8), connected downstream of said preheater (1) with respect to said direction of flow of the combustion fumes (10); a system of heat treatment (9, 13) of the fumes leaving the catalytic system of removal of NOx (8), said apparatus providing that the catalytic system of removal of NOx (8) and the system of heat treatment (9, 13) of the fumes leaving the catalytic system of removal of NOx (8) are integrated in a single tower structure (12). |
