ABB Expert Optimizer MPC for Alternative Fuel Substitution in Cement Kilns

This document discusses how Model Predictive Control (MPC), implemented via ABB's Expert Optimizer platform, enables cement plants to increase alternative fuel substitution rates up to 100% by stabilizing precalciner temperature despite high calorific variability. It addresses the challenges of using alternative fuels, such as process instability and refractory wear, and presents results from installations in Europe and the USA.
