A system for the preparation of a combustible gaseous mixture from solid or liquid fuels, in which an artificial gravitational field is used, generated by a rotating cup-shaped grate (1) for supporting a travelling bed of granular refractory material (sand), the fuel lying upon said bed. A gaseous medium is supplied to the outside of the support grate (1) at a pressure higher than the one prevailing inside said grate and results in a velocity of said medium such, that only very small particles of the travelling bed are entrained, while the temperature of the combustible mixture remains in the order of 900 DEG C. |
