Coke oven gas (COG) is used as fuel for the calcination of limestone in the vertical kilns at this steel mill in India. The COG is boosted to a pressure of 2 kg/cm2 in a set of rotary vane boosters. The gas then goes through an orifice to the kiln for combustion. The gas pressure must be maintained to insure uniform calcination.
The rotary kiln process is favored in North America for its ease of operation and versatility. Typical temperatures for a rotary coke calcining kiln are between 2200°F (1200°C) and 2400°F (1315°C). Alumina-silica refractories in the 40% to 70% Al2O3 range are appropriate for these normal operating temperatures.
coke or graphite needle-grade coke depending upon its physical and chemical characteristics with needle-grade coke having a higher purity than anode-grade coke which is used in electric furnaces in aluminum and steel smelting.
