The process for determining and controlling the fuel mass flow in partial oxidation and gasification of a fine-grained to powdery fuel includes particularly drawing the fuel from the supply vessel through a single outlet pipe and feeding the fuel to a distributor, in which a plurality of individual supply lines are connected to the individual burners, the fuel mass flow rate in the supply lines depending on the speed measured there and the radiometric density measurement being determined in the outlet pipe of the supply vessel. For control of the fuel mass flow a stepwise regulation depending on the crude gas flow produced in the gasification unit is thus provided.

A method of determination and monitoring of a fuel mass stream supplied for partial oxidation of fine-grain up to pulverized fuels to a gasifier includes determining a total density .rho..sub.tot of a fuel stream conveyed by a fluidizing gas in an outlet conduit of a fuel bin with the aid of a radiometric density measurement, subsequently determining a total volume stream q.sub.v.sbsb.tot of said stream by a differential pressure measurement, determining a difference between volume streams of a fluidizing gas supplied to the fuel bin q.sub.v.sbsb.gas supplied and discharged from the latter q.sub.v.sbsb.gas discharged by differential pressure measurements, determining a volume stream of the fluidizing gas q.sub.v.sbsb.gas fuel in accordance with the following equation:
