All of these provide scientific basis for development of the novel cyclone. At last, according to the thorough study of gas-solid process, The cyclone shape and size are improved, and the cyclone performances are taken better. The technique of cyclone with down-flow is updated, and applied in CFB boilers, retrofitting old boilers, CFB pulverized-coal gasifier, flue gas cleaner, and so on. The successful operation of 75T/h CFB boiler indicts that the novel technique tends to ripe.
