"Mid-kiln firing" means, for the purposes of 35 Ill. Adm. Code 217, Subpart T, a secondary firing in a kiln system by injecting fuel at an intermediate point in the kiln system using a specially designed fuel injection mechanism for the purposes of decreasing NO_x emissions through burning part of the fuel at a lower temperature, and reducing conditions at the fuel injection point that may destroy some of the NO_x upstream in the kiln system.
