Abstract
A method and apparatus is detailed for cooling hot bulk material disposed in gas-permeable cooling buckets which travel from a charging zone to a discharge zone, with the cooling buckets in communication with a plenum chamber having integral blower means for forcing cooling gas through the bulk material. The volume of cooling gas forced through the bulk material proximate the charging zone is substantially less than the volume of cooling air which is forced through the bulk material over the rest of the travel path. This results in a substantial reduction in the particulate emission from the bulk material. A cooling gas throttling means is disposed in the plenum chamber between the charging zone and the discharge zone for restricting the volume of cooling gas at specific areas along the travel path.
