| Abstract: | For the annual output of 1.2 million tons of hot metal produced by two blast furnaces with a maximum 140 kg coal injection per ton of hot metal, 20-24 t/h of pulverized coal is required. After capacity expansion revamping, the annual output of hot metal by both BFs will reach 2.1-2.3 million tons and the quantity of pulverized coal will be increased up to 50-55 t/h accordingly. Thus, the pulverized coal preparation system shall be extended from one system to two systems with the rich-phase delivery technique. |
