Abstract
Method for supplying fuel material to a gasification reactor into which a mixture of finely powdered fuel material, in suspension in a liquid phase, is charged inside a pressurized combustion chamber into which the combustion-supporting gas is injected and constituting the reactor, by means of a screw conveyor producing a continuously fluid-tight plug by compression of the driven material. By intermeshing at least two overlapping screws with identical threads rotated in the same direction, a wringing of the mixture introduced through an input orifice is compressed by regulating the flow rate of the mixture supply and the rotary speed of the screws so that, for a given flow rate of material, the plug constituted in a braking zone is at a given pressure and contains a certain proportion of liquid phase. The additional amount of liquid phase is expelled into the braking zone and reascends upstream into a drive zone where it is removed through orifices formed in filtering parts of a sleeve.
