DEVICE AND PROCESS FOR FEEDING COAL INTO A SHAFT FURNACE

摘要

The proposal is for a device and a process for feeding coal dust into a shaft furnace in which coal dust is fed into the shaft furnace by means of a carrier gas through a feed line (20). The coal dust is heated, before entering the feed line (20), preferably in several stages in a plurality of containers (4, 10, 14) one behind another in which there are heating elements (28, 42, 44).
