Abstract

A cooler for hot material such as cement clinker with an arrangement for recycling cooling air. The cooler includes a housing divided into an upper material chamber and a lower plenum chamber by a gas permeable grate which supports and advances the material through the material chamber. Ambient cooling air is blown through the hottest and the coolest material. Two air recirculation circuits are employed. The ambient air blown through the coolest material is divided so that a portion goes to each recirculation circuit. One recirculation circuit returns air to the plenum chamber at a point where it will pass through the material to be cooled and then be conducted to the furnace. The other recirculation circuit returns air to the plenum chamber at points where it will pass through the material and some of it will be conducted to a furnace, while the remaining air will be returned to the recirculation circuit. An indirect heat exchanger is mounted in one of the recirculation circuits.
