Method and plant for coal grinding in inert or non-inert operation

摘要

The invention relates to a method and a plant for coal grinding in the inert or non-inert operation, in which a part of the pulverized coal produced in a mill is fed to a separator for separating a Feinstkorns. The ultrafine grain is fed to a hot gas generator with solid fuel burner to heat the recirculated process gas and feed it back to the mill. The self-produced coal dust is thus used for hot gas production.
