Method and device for the introduction of solid, flight enabled fuel into the calcinator of a cement production line

摘要

A method for the introduction of solid, flight enabled fuel (17) into the calcinator (10) of a plant for the production of cement clinker from raw cement meal, the preheated in a heat exchanger system, in the calcinator supplied with the fuel and calcined in a rotary kiln is burned to cement clinker, wherein the preheated cement raw meal (12) via a on the outside of the calcinator (10) and arranged with the latter by a wall opening (10a) meal intake box (13) is connected with an oblique raw meal and deflector slide into the reaction section of the calcinator is introduced, characterized in that the air-floatable fuel (17) in the flour entry box (13) and inserted there with the preheated raw meal (12) premixed and then over the deflector slide (15) into the reaction section of the calcinator (10) for the formation of a uniformly distributed gas - raw meal - solid fuel - suspension is introduced, wherein the introduction in the flour entry box (13) is carried out pneumatically, and wherein the conveying speed of the pneumatic transport of the air-borne fuel (17) before entry into the meal intake box (13) is reduced.
