    Tires are burned in conjunction with the coal/coke, as is the case with the cement kilns. However, the steel belts in the tires must be removed in a pre-processing step to avoid fouling the equipment. Unlike the situation in cement manufacturing, the steel in the tires has no use in the production of electrical power, and only serves to hinder it
