The mathematical model of a steam boiler has been developed to analyze water-wall slagging and superheater fouling. The computer based boiler performance monitoringsystem has been designed to perform thermal-hydraulic calculations of the boiler in on-line mode. Measurements of temperatures, pressure, flows, and gas analysis data are used to perform heat transfer analysis in the furnace and convection pass. The state of boiler slagging and fouling, including optimization of sootblowing, can be evaluated from practical plant measurements. The slag monitoring system can be used to detect the build-up of slag and ash deposits in boiler furnaces and steam superheaters and to guide sootblower operation. In order to raise the boiler efficiency and to reduce fuel cost, the sootblower can be run according to the information obtained from the developed system.
