Abstract
A method of optimizing the scheduling time between sootblowing operations in a boiler having a plurality of heat traps, comprises measuring the instantaneous efficiency for each heat trap of the boiler, using a filter constant and the amount of load under which the heat trap is placed to calculate an average slope for the loss of efficiency between sootblowing operations and calculating an optimum scheduling period between sootblowing operations as a function of a cost factor reflecting the cost of a sootblowing operation, the duration of the sootblowing operation and the slope.
