(1) high-order conveying.
5. a kind of semicoke circulation composite heating technique of oil shale retorting semicoke rotary furnace according to claim 1, it is special
Sign is：When oil shale tailing particles are delivered to material distributing valve (8) mouth of swinging gas retort outer barrel (1), oil shale tailing particles
In a part scraped by material distributing valve (8) in valve port, inner cylinder (5) is entered to the feed pipe (9) of inner cylinder by outer barrel；Oil shale tail
Solid impurity particle directly heats as high-temperature heat carrier into inner cylinder (5) to the undecomposed oil shale of inner cylinder；Not by sub-material
The oil shale tailing particles that valve (8) is scraped in valve port enter feed opening (10) and discharged by exporting.
