ABSTRACT:
The invention relates to the cooling of hot, layered, granular material supported on an air permeable grate through which cooling air passes constantly. Some zones of the material layer have a higher temperature than other zones. Pulses of additional cooling air are passed through the higher temperature zones at such velocity as to enhance cooling and to relayer the material at such zones. In this way the degree of recuperation of the grate cooler can be substantially improved.
