Abstract

. ` A process for calcining mineral raw materials is performed in a two-shaft furnace wherein each of the shafts are alternately used as the calcining shaft and as the counterflow shaft. Fuel is supplied in the calcining shaft by means of burners at the end of a preheating zone and the mineral raw material is calcined in a calcining zone. Generated exhaust gases flow upwardly into the counterflow shaft, heat up the raw material in the shaft and leave through an exhaust. The calcined raw material is passed through an after-deacidification zone and, subsequently, through a cooling zone in which it is cooled by means of cooling air which is blown in from below. After removal of dust, the heated cooling air is either entirely or partially conveyed either directly into a raw material preheater or it is utilized in a recuperator for heating combustion air.
