<p>The aim of the invention is to control the operation of a bulk good grate cooler for cooling hot cement clinker, for example, in a process-controlled manner in order to ensure that the volume flows of cooling air (21) in all areas of the cooling grate and/or the residence time in the respective area of the bed of the goods to be cooled can be matched to the cooling requirements occurring in each area. According to the invention, a control intervention is carried out during the operation of the grate cooler with respect to the respective local cooling air volume flow (21) and/or with respect to the respective local speed of conveyance of cooling grid according to the respective bulk good bed height measured per area and/or the bulk good bed temperature and/or the cooling air through-flow resistance such that if a modification occurs in one or several of the measured parameters i.e. bed height, bed temperature and through-flow resistance, the respective local cooling air volume flow (21 ) and/or the conveyance speed of the grate system is altered.</p> |
