A CRITICAL-REVIEW OF COMPUTER MODELING OF KRAFT RECOVERY BOILERS

This paper assesses the state of the art of modeling recovery boilers in the context of what such models need to do. A review is made of the type of information needed to improve recovery boiler operation and t he capability of existing recovery boiler models, especially furnace m odels, to supply this information. Gaps where additional fundamental i nformation is needed or where models are lacking are identified. The i mpediments to more extensive use of models are noted and means for ove r-coming these impediments suggested. Critical areas requiring further work are delineated.
