This study introduces a Kiln Expert System (KES) that leverages symbolic artificial intelligence, real-time data analysis, and adaptive algorithms to dynamically stabilize key variables such as calciner temperature and oxygen levels. By incorporating a higher proportion of alternative fuels (ATFs), KES not only reduces variable costs but also minimizes the carbon footprint and strengthens the competitive positioning of operations.Deployed in a facility with a five-stage preheater and a multistage calciner, the KES fine-tunes the combustion parameters in real time to maintain high production standards, improve performance, and adapt to changing operational conditions. This innovative approach demonstrates how AI-driven systems can transform process management by enabling precise control, optimizing resource use, and aligning industrial practices with environmental goals.
