Abstract of the Disclosure The known pulverized coal combustion method including the steps of separating pulverized coal mixture gas ejected from a vertical type coal grinder containing a rotary type classifier therein into thick mixture gas and thin mixture gas by means of a distributor, and in- jecting these thick and thin mixture gases respectively through separate burner injecting ports into a same furnace to make them burn, is improved so as to reduce both an unburnt fuel content in ash and a nitrogen oxide concentration in exhaust gas while maintaining excellent ignition characteristic. The improvements reside in that an air-to-fuel ratio of the thick mixture gas is chosen at 1 - 2, while an air-to-fuel ratio of the thin mixture gas is chosen at 3 - 6, and the range of a degree of pulverization of the pulverized coal is regulated at 100 mesh residue 1.5% or less. The degree of pulverization of the pulverized coal fed to the distributor is regulated either by adjusting a rotational speed of the rotary type classifier or by adjusting the angles formed between classifying vanes rotating about the axis of the rotary type classifier and the direction of rotation.
