The pulverized coal preparation system with self-cycling fume design of Degang-steel's 4# BF
Pulverized coal preparation system with self-cycling fume design of Degang-steel's 4# BF is introduced and summarized.The process uses fully fired blast furnace gas,medium speed mill,and bag powder collection,the volatile content of ground bituminous coal is 25％.During the stable production,the oxygen content at the end of the system is controlled within 12％,and the dust emission concentration is less than 10 mg/Nm3.Production prac-tice has shown that the process without dehydration device and fully burning blast furnace gas is safe and reliable,meeting production requirements.
