Changing process priorities when firing alternate fuels

A presentation is given on process modifications to accommodate alternate fuels and firing methods. Discussion is made on process control strategy that makes combustion control the priority, burner modification to boost flame temperature, and the addition of energy for mixing of the combustion gasses to minimize excess air requirements. The implementation of these process modifications considers clinker quality, emissions and high alternate fuel substitution. Results from several facilities are included.
