Abstract

Product gas is produced by partial gasification of coke or coal. The coke or coal is admitted in particulate form into a gasification zone where it undergoes partial gasification. The residue of coke or coal is then forwarded into a combustion zone where it is combusted to liberate heat. A gaseous heat carrier is first passed through the combustion zone to become heated therein, is then passed through the gasification zone to sustain the partial gasification process, and is then recirculated into the combustion zone to be reheated.
