COOLER FOR COOLING CLINKER AND METHOD FOR OPERATING A COOLER FOR COOLING CLINKER

摘要

The present invention relates to a method for operating a cooler (10) for cooling clinker, in particular of a cement making plant, comprising the steps of conveying the clinker to be cooled along an aeration grate (18), through which cooling air passes in cross-flow, and determining the temperature distribution in at least one measuring plane (38-48) above the aeration grate (18), characterized by closed-loop/open-loop control of at least one operating parameter from the conveying rate of the clinker and/or the flow rate of the cooling air of the cooler (10), according to the temperature distribution determined. The invention also relates to a cooler (10) for cooling clinker, in particular of a cement making plant, comprising an aeration grate (18) for conveying the clinker in a conveying direction, and at least one fan (32) for generating a cooling air stream, which passes through the aeration grate (18) in cross-flow, a measuring plane (38-48) with at least one temperature measuring device for determining a temperature distribution in the measuring plane (38 - 48) being arranged above the aeration grate (18), and an open-loop/closed-loop control device (50) being provided and designed in such a way that it controls the conveying rate of the clinker and/or flow rate of the cooling air stream in an open-loop or closed-loop manner according to the temperature distribution determined.
