Zusammenfassung: | FIELD: melting-gasification sets. SUBSTANCE: method of recirculation of fine-grained hard substances 4 removed with gas from outlet zone of reaction reservoir 1 to recirculation zone of reaction reservoir 1 includes separation of hard substances 4 in separator 3 and their accumulation in accumulation reservoir 8, wherefrom hard substances are delivered to reaction reservoir 1 again by means of transportation gas. To enhance efficiency of hard substances separator 3 without additional load on reaction reservoir 1, auxiliary gas flow 23 is passed through hard substances separator 3 over closed circuit in direction of flow of hard substances 4 irrespective of gas flow in reaction reservoir. EFFECT: enhanced efficiency. 20 cl, 5 dwg |
