A pulverized coal injection system consists of a pulverizing mill, a filtering system, storage tanks, and a blast furnace. Coal comes in through a bunker and is pulverized in a pulverizing mill. The pulverized coal is carried by hot air into a storage tank for . drying, and the hot air is emitted to the atmosphere through a bag filter. Bag filter
