    Delayed petroleum coke is calcined in an internally-fired vertical shaft kiln. A downwardly-moving bed of green coke is preheated in the top of the kiln by rising combustion gases, then heat soaked at calcining temperatures in the intermediate section of the kiln, and finally cooled by recycle gas moving upwardly from the lower part of the kiln.

    "All water used on site is recycled and grey water is fed back into our production system where it cools the calcined coke," says Picard. And earlier this year, the company celebrated Earth Day by changing over to a bottle free cooler system. "We were using more than 600 large water bottles per year," explains Picard.

    Calcined coke is a competitive material for making carbon anodes for smelting of alumina to aluminum. Calcining is an energy intensive industry and a significant amount of heat is exhausted in the calcining process. Efficiently managing this energy resource is tied to the profit margin and survivability of a calcining plant.

    Air can be injected through the kiln shell to burn a portion of the volatile matter in the kiln providing usable heat to the kiln. Cooling: Once the calcined coke is discharged from the kiln, the coke is cooled in a rotary cooler. At the feed end of the cooler, water is sprayed on the calcined coke to cool the coke to acceptable temperatures.
