Method of producing pulverized coal as fuel for pulverized-coal pilot burners

摘要

A method of producing pulverized coal as fuel for pulverized-coal pilot burners of pulverized-coal annular burners or of systems thereof in a power plant having auxiliary steam generators. The raw coal undergoes or is subjected to a pulverizing-drying, and the pulverized coal which is produced is separated off in a separating system and is supplied either directly or after temporary storage by means of a suitable transporting system to the pilot burners. The thermal drying energy for the pulverizing system is taken from the flue gases of the auxiliary steam generator. The foregoing method can also be utilized for pulverized-coal burners or systems thereof.
