FLUID BED REACTOR WITH FURNACE-TYPE PULSED HEAT TRANSFER MODULES Russian patent published in 2012 - IPC B01J8/18 F27B15/00 C10J3/56 

FIELD: process engineering.

SUBSTANCE: invention may be used in chemical industry. Proposed fluid bed reactor 300 comprises reaction vessel 302 with first wall part and second wall part, first heat transfer module 310 connected to vessel 302. First heat transfer module 310 comprises first pulse furnace 312 connected to first acoustic chamber 311 with first and second faces. First pulse furnace 312 comprises, at least, one exhaust pipe 314 terminating in first acoustic chamber 311 between first and second faces, and multiple heat transfer pipes 326. Every said heat transfer pipes 326 stays in fluid contact with acoustic chamber 311 via said wall part. Combustion products from exhaust pipe 314 along first channel of every heat transfer pipe from first wall part and, then, along second channel toward wall first part. Resonance tube of first pulse furnace 312 does not extend inside reaction vessel 302.

EFFECT: efficient conversion of carbides into gas.
