ABSTRACT:
The temperatures of the primary carrier gas supplied to a coal pulverizer and the fuel stream discharged from the pulverizer are controlled to keep the fuel stream temperature within a predetermined safe and efficient operating range regardless of the rate at which coal is fed to the pulverizer. A carrier gas temperature versus coal feed schedule is established and used for temperature control. If fuel stream temperature departs from the predetermined operating range, the established schedule is automatically corrected.
