摘要： The proposed method is characterized by raising the temperature of heating of a coal charge in each subsequent stage by a value which is somewhat less than the temperature rise in the preceding stage so that in the next to last stage there is provided heating of the coal charge to a temperature at which the resin vapours start to isolate from the coal charge. The method is also characterized in that the circulating gaseous heat carrier of the nest to last and the last stages of heating is purified from impurities prior to the recirculation. In order to carry this method into effect, the multistage apparatus is provided with a chamber for purification of the gaseous heat carrier from impurities arranged between two groups of chambers for successive step-wise heating of the coal charge.
