Abstract:
1. A method for determining a set of desired cleanliness levels in a boiler, the boiler defining one or more heat zones, each heat zone having an adjustable cleanliness level associated therewith, the performance of the boiler being characterized by boiler performance parameters, the method comprising: (a) receiving a boiler performance goal corresponding to at least one of the boiler performance parameters, wherein the boiler performance goal is indicative of a desired objective for the at least one of the boiler performance parameters; (b) receiving data values corresponding to boiler state variables and to the boiler performance parameters, said boiler state variables including current cleanliness levels associated with each heat zone of the boiler; (c) determining the set of desired cleanliness levels to satisfy the boiler performance goal using the received data values and the received boiler performance goal, wherein determining the set of desired cleanliness levels includes coordinating the cleanliness levels for the one or more heat zones to satisfy the boiler performance goal; and (d) outputting the set of desired cleanliness levels to a sootblowing subsystem including one or more sootblowers and a controller for controlling the one or more sootblowers to maintain the set of desired cleanliness levels in the boiler.
