Abstract
A process and apparatus for the gasification of partially dried fuel with hot gas which has been heated by bringing it into contact with an inert hot heat carrier. The fuel gases generated during the gasification process are further combusted and utilized for heating the inert heat carrier. The process and apparatus can be combined with a process and apparatus for generating steam from wet fuel wherein water is evaporated from the wet fuel by bringing the fuel into direct contact with superheated steam. The steam is superheated by bringing it into contact with a second hot heat carrier. The second heat carrier is heated by bringing it into direct contact with the fuel gas produced by combusting the fuel gas from the gasification process.
