This paper proposes an integrated monitoring system that combines fuzz y logic and an improved Group Method of Data Handling (GMDH) algorithm. First, 18-rule -based fuzzy logic diagnostic model identifies the operational state of the calcination zone with 94.2% accuracy. Second, an enhanced GMDH algorithm with novel data preprocessing and f eature selection mechanisms serves as a soft sensor for predicting CO₂, CO, and O₂ concentrations . Experimental results from a 10,000-ton/year vertical lime kiln demonstrate that the improved GMDH achieves mean absolute errors of 1.5% for CO₂, 2.9% for CO, and 3.0% for O₂, representing a 43.2% improvement over conventional methods. Field application shows 8.3% reduction in fuel consumption and 15.2% reduction in CO emissions, confirming the system's practical value for industrial process optimization. }, issn = {3032-7059}, pages = {12} doi = {10.9767/jcerp.20741}, url = {https://journal.bcrec.id/index.php/jcerp/article/view/20741} }
