Abstract

To reduce the heat loading in the Tilden Mine kilns caused by the burning of coal, which results in a rapid and significant build-up on the kiln lining, internal carbon was added to the green ball prior to balling. Intensive laboratory testing led to three short-term full-scale plant tests that were successfully conducted. Appropriate environmental permits were obtained to allow Tilden to use internal carbon on a continuous basis. Findings concerning carbon addition rates, red...
