The primary air supply is used mainly to burn the fuel oil or the natural gas which due to Alcan's third air technology is used only to initiate the calcination process. Calcined coke falls over the lip of the kiln into a rotary cooler for direct water quenching which decreases the coke temperature to about 200°C.

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.
