PROCESS FOR REGULATING A CIRCULATING FLUIDISED BED AND USE OF THE PROCESS

摘要

In this process, at least part of the pure gas stream discharged from the cyclone (2) is used as at least part of the carrier gas at least in one spot of the circulating fluidised bed, the pure gas used as part of the carrier gas is mixed in an injector mixer (8) with 10 to 90 wt % propellant gas, relative to the volume of the pure gas stream discharged from the cyclone (2), before the supply line into the circulating fluidised bed, and the mixture is supplied as carrier gas to the circulating fluidised bed.
