METHOD FOR THERMAL DECOMPOSITION OF SOLID CARBON-CONTAINING MATERIALS WITH USE OF SOLID HEAT CARRIER, PLANT FOR EMBODIMENT OF THE METHOD, REACTOR FOR DECOMPOSITION OF SOLID CARBON-CONTAINING MATERIALS AND HEATER-GASIFIER OF SOLID HEAT CARRIER

摘要

FIELD: treatment of solid carbon- containing materials with use of solid heat carrier for thermal decomposition of low-grade solid fuels, solid household and industrial wastes. SUBSTANCE: plant for embodiment of the method of thermal decomposition of solid carbon-containing materials with use of solid heat carrier has reactor 1 with vertical body 2 or variable cross-section with branch pipe 3 for withdrawal of vapor-gas products from the upper part, heater-gasifier 4 with vertical body 5 and branch pipe 6 for withdrawal of gaseous products of gasification. Heater-gasifier 4 is located above reactor 1 and coaxial with it. Pressure standpipe 7 for introduction of solid heat carrier to heater gasifier 4 is connected with its upper end to the lower part of body 5 of heater-gasifier 4 and with its lower end, to the lower part of body 2 of reactor 1. Discharge standpipe 8 for withdrawal of heated solid heat carrier is connected with its upper end to the lower part of body 5 of heater- gasifier 4, and with its lower part, to the middle part of body 2 of reactor 1. EFFECT: higher efficiency. 18 cl, 7 dwg
