Zusammenfassung:	The invention relates to a method of gasifying raw materials comprising combustible components. The inventive method is characterised in that the heating of the raw materials and endothermic drying, pyrolysis and gasification reactions by vapour take place in at least a first compartment (4), or reactor, of a horizontal rotary cylindrical furnace (1). According to the invention, the thermochemical treatments, which are performed in the reactor, receive solely sensible heat which is conveyed by a solid heat-transfer medium (2) that is cooled in said reactor by between 40 and 70 DEG C to a temperature which is less than 900 DEG C and less than the melting temperature of the ash generated. The aforementioned solid heat-transfer medium (2) is itself heated by a part of the gaseous fuel, which is supplied by the reactor, in a second compartment (3) of the horizontal rotary cylindrical furnace, called the heater, said heat-transfer medium (2) being moved continuously between the two compartments (3, 4) during operation. The invention also relates to an installation that is used to carry out said method. La présente invention concerne un procédé de gazéification de matières premières présentant des constituants combustibles caractérisé en ce qu'un chauffage des matières premières ainsi que des réactions endothermiques de séchage, pyrolyse et gazéification par ladite vapeur se déroulent dans au moins un premier compartiment (4) d'un four cylindrique horizontal rotatif (1), appelé réacteur, où des traitements thermochimiques reçoivent de la chaleur exclusivement sensible, cédée par un solide caloporteur (2) qui est par là refroidi par 40 à 70 °C à une température située au-dessous de 900 °C et au-dessous de la température de fusion des cendres générées, ledit solide caloporteur (2) étant lui-même chauffé par une partie du combustible gazeux fourni par le réacteur dans un deuxième compartiment (3) dudit four cylindrique horizontal rotatif, appelé réchauffeur, tout en présentant un déplacement continuel du caloporteur (2) entre les deux compartiments (3,4) lors du fonctionnement. L'invention concerne également une installation pour la mise en oeuvre du procédé.
