Abstract
A method for predicting the optimum cycle time to schedule sootblowing using on-line process measurements. The optimum cycle times dynamically adjust to changing conditions resulting from boiler operation, fuel changes, or seasonal changes. The optimum cycle time is calculated four times per second for each heat trap of a boiler (10). The optimum conditions are based on economic criteria which account for heat trap fouling, rate of fouling of other heat traps (12, 13, 14, 16, and 18) within the boiler, and on-line boiler incremental steam cost.
