Abstract
Described is a method as well as a cooler () for cooling hot particulate material which has been the subject of heat treatment in an industrial furnace, such as a rotary kiln () for manufacturing cement clinker, by which method the hot material from the kiln () is directed to an inlet grate () in the cooler (), in which cooling air from an underlying compartment () is led via a number of channels () through gaps () in the inlet grate for cooling the hot material and where compressed air from a separate system () via a number of ducts () can be intermittently injected into the material on the inlet grate (). The channels () for cooling air are blanked off in connection with the injection of compressed air.
