Abstract:
A method and system for controlling and providing guidance in sootblowing based on continuous plant monitoring and model calculations. The continuous monitoring of plant conditions is through a plant distributed control system (DCS) which communicates with a computer. The conventional measurements of a DCS such as flow, pressure and temperature and sootblower status data are input into the computer. These valves are validated for accuracy. To predict the effects of fouling a plant model is utilized. The model predicts the rate and effect of fouling on energy distribution in the boiler. The model then predicts the effect that sootblowing of each section will have on the boiler performance. A comparison of the predicted and observed effects are used to update the fouling model and maintain consistency with the actual performance of the boiler. This information is presented to the boiler operator to assist in enhancing the boiler efficiency and maintain steam temperatures within established control ranges.
