ABSTRACT OF THE DISCLOSURE The disclosure describes a plant for the pressure gasi- fication of fine-particle fuels, in which the fine-particle fuel is fed to the reactor from a pressure tank having a level control ler, by means of a vehicle gas fed via a conduit, said fuel being fed via a fuel feed conduit, while the gasification agent is fed via another conduit in a predetermined ratio by volume according to the amount of fuel supplied. me fuel feed conduit contains a system for measuring the fine-particle fuel present in a spe- cific cross-section of the conduit, said system being based on the principle of absorption of electromagnetic radiation by the fuel, and the measuring system is connected to a process computer which forms the reciprocal (U1) of the value (u1) obtained in the measuring system. The conduit for supplying the major proportion of vehicle gas contains a system for measuring the volume supplied per unit of time and said system is also connected to the process computer and transmits the measured value to the latter in the form of a voltage (U2). The computer is so constructed that to- gether with a predetermined comparison voltage (Uv) it forms the difference (U2 - Uv) and the product [U1 ? (U2 - Uv)] for all values of (U2) greater than (Uv) and in accordance with the value of the product [U1 ? (U2 - Uv)], controls the valves for the feed conduits for the proportion of vehicle gas which loosens the fuel in the pressure tank and discharges it therefrom, and the valve for the supply of gasification agent.
