Abstract: The present invention concerns a process for purifying a flow of combustion fumes from a clinker production plant comprising the following operating steps: a) removing dust at a temperature comprised between 250 and 400° C. from a flow of combustion fumes exiting from a suspension preheater with formation of a flow of combustion fumes free of dust; b) carrying out on said flow of combustion fumes free of dust a selective catalytic NOx reduction treatment with a reducing agent, with formation of a purified flow of combustion fumes. The present invention also concerns an apparatus for carrying out the aforementioned process.

Abstract: The present invention concerns an apparatus for the production of clinker from raw meal, comprising: a rotary kiln (8), optionally a precalciner; a multi-stage cyclone preheater (9) connected downstream of said rotary kiln (8) with respect to the direction of flow of the fumes (11) of a combustion taking place in said kiln (8); an electrofilter (10) connected downstream of said preheater (9) with respect to said direction of flow of the combustion fumes (11); characterized in that it comprises a first inlet (17) for feeding raw meal to said combustion fumes (11), said inlet (17) being arranged downstream of said preheater (9) and upstream of said electrofilter (10) with respect to said direction of flow of the combustion fumes (11), and in that it comprises a second inlet (18) for feeding partially preheated raw meal (14) from said electrofilter (10) to said preheater (9). The present invention also concerns an improved process for the production of clinker from raw meal.
