A method for the gasification of solid fuels such as bituminous coal, lignit ecoal, and petroleum coke in the flue stream with an oxidizing medium containing free oxygen, by partial oxidation at pressures between atmospheric pressure and 80 bar and at temperatures between 1,200 and 1,900 degrees. The method which includes the principle process steps of pneumatic metering of pulverized fuel, gasificati on reaction in a reactor with cooled reactor chamber contour, quencher cooling, crude gas scrubbing, and partial condensation, includes the specific steps of: feeding a pulverized fuel with a water content of < 10 wt.%, preferably < 2 wt.%, and a grain size of < 200 mum, preferably 100 mum, to a pneumatic met ering system, the pulverized fuel from a bunker (1.1) reaching at least one pressurized sluice (1.2) and being subjected to a condensate-free gas at a pressure between atmospheric pressure and 80 bar, and being fed to a metering tank (1.3) into the bottom of which is f ed an inert gas (1.8), so that a fluidized bed with a density of 350 to 420 kg/m<3> is formed, feeding fluidited pulverized fuel through a transport pipe (1.4) to a burner of the reactor (2), subjecting the fuel together with an oxidizing medium containing free oxygen , to partial oxidation in a reaction chamber (2.3) of the reactor with cooling shield (2.4), with the ash of the fuel being melted and transferred together with the hot gasification gas through a discharge device (2.5) of the reactor into a quenching chamber (3.1) of a quenching cooler (3), quenching the gasification gas and ash at a temperature between 180 and 260 DEG C, and in the quenching cooler, and subjecting the quenched steam-saturated crude gas to a crude gas scrubber (4) or to a mechanical dus t separator to cleanse it of entrained fines.
