FIELD: chemical engineering. SUBSTANCE: in order to remove condensed particles from working surfaces of quench containing concentrically mounted cooled tube and, disposed therein in spaced relation to it, cooled rod. The latter has axial through passage and, connected to it, connecting pipe to feed solid particles. Axial passage of rod communicates with connecting pipe serving to remove gas pyrolyzate through annular gap between rod and tube. EFFECT: enhanced efficiency of quench operation. 1 dwg
