The Process Modeling and Simulations for the Fault Diagnosis of Rotary kiln Incineration Process

This paper presents a rule-based and on-line expert system, named RKEXPERT, to supervise the combustion operations of a pilot scaled rotary kiln incinerator with a special focus on the fault diagnosis and feedback controls. The combustion process is routinely susceptible to a large number of operational problems. Knowledge base of RKEXPERT contains the heuristics and insights of experienced operators and also the knowledge necessary for problem solving related to diagnosis and control. The whole knowledge in this system was organized into a unique hierarchical structure and represented using an IF-THEN rule-based formation. Based on the rule-based expert system by on-line mode, the intelligent process operation aid system for the combustion plant was completed to provide integrity in optimal operation and control.
