How Is Metallurgical CoalCoking CoalUsed - The Balance. Jul 15, 2019 Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking.Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces.
A proposed upper limit for pulverized coal injection, which would burn completely in the tuyere combustion zone, is estimated at 180 kgt when the fuel rate is 500 kgt. An upper limit for pulverized coal grain size is 0.7 mm.7 Calculations based on furnace trials have shown that pulverized coal can replace up to 30-
pulverized coal grain size is 0.7 mm.7 Calculations based on furnace trials have shown that pulverized coal can replace up to 30- 50 of the coke previously used in blast furnaces employing oxygen enriched blast, without impairing productivity or hot metal quality. A pulverized coal injection
