Lime kiln preheaters are used to "preheat" the limestone prior to the limestone being fed into the kiln. Hot kiln exit gases that might otherwise be exhausted to the environment are used to heat the limestone. This improves operating efficiency and reduces operating costs. Lime preheater floors are very abrasive service environments.
