Abstract
A method for calcining carbonaceous materials in a rotary kiln is disclosed. An oxygen injection lance provides oxygen through the wall of a firing hood and into the carbonaceous bed, which is at an elevated temperature. The oxygen burns a portion of the carbonaceous material, providing the necessary heat for calcining the remainder of the carbonaceous materials in the kiln.
