Implementation and industrial experiences of advanced control and monitoring in coal injection

This paper summarizes the implementation and industrial experiences of a mo del-based control and gas-leakage detection system in a coal injection plan t. It describes how advanced control and monitoring can be implemented in a n industrial environment while taking human-machine interface aspects into consideration. The operation of the advanced and the conventional concept a re compared regarding evaluation data, experiences and observations of oper ators and maintenance personnel. It is shown that the advanced control and monitoring system improves plant performance without disturbing routines in plant operation and, moreover, is positively accepted by the plant operato rs.
