    摘要: A method of cooling and dedusting degasification gases which escape from coal degasification chambers particularly gases which are obtained in high temperature or low temperature carbonization of bituminous and subbituminous coals and which pass from degasification chambers through risers and bends into collection mains and in the bends or in the collecting mains themselves which comprises directing crude tar having a temperature in excess of 50.degree. C. and lower than 170.degree. C. into the bends and collecting mains either alone or with water added which has a temperature and is of a quantity such that it completely evaporates in the collecting main. An apparatus for carrying out the method includes means for spraying either the tar or the tar plus water into the collecting main containing the degasification gases and passing the gases and the liquids from the main into a cooler to separate the gases and a liquid condensate and the tar oil from the condensate and which includes means for directing the crude tar through a separator for separating the heavy tar from a remaining portion of the tar and further directing the remaining portion through a supply tank and a centrifuge for removing solid matter therefrom.
