The kiln inlet flow rate is calculated based on the petcoke firing in the kiln and calculated combustion products and excess air at the kiln inlet. Other inputs are tertiary air and transport air obtained from the plant data. All inputs along with their temperatures, c p values, and enthalpies are fed to the stoichiometric MS excel model.
