EFFECTS OF BINARY COMPONENT ON PARTICLE VELOCITY AND COKING BEHAVIOURS IN DOWNERS

摘要

The coking observation and particle flow behaviour in both thermal plasma and cold Plexiglas downers were studied for the first time on a binary particle system, formed by injecting coarse inert particles as coking carrier and wall scourer and fine reactant coal powders into the downer, which demonstrates that this scheme is a good selection to prevent coking in the thermal plasma coal cracking process.
