摘要： PURPOSE:To suppress an unburnt component concentration in ash, an NOx value to specified values and to optimally maintain a thermal efficiency by subjecting an injection time interval of a soot blower to fuzzy inference based on a specific parameter, and deciding a next injection position of the blower. CONSTITUTION:An operation history recording means 1 records a past operation history of a plurality of soot blowers installed in a blower. A contamination degree deciding means 2 decides whether a temperature difference of inner and outer walls of a furnace metal is out of a specified value or not, and a function recorder 3 records the number of cases decided as out of the specified value, a furnace heat recovery rate, unburnt component concentration in ash and membership function for a load. A fuzzy inference means 4 infers and outputs an injection time interval of the blowers based on a grade value of the recording function. A priority order of the blowers to be injected is decided by an infection position deciding means 5 in response to a temperature difference measuring position of the metal decided as out of the specified value by the means 2 and the recording operation history.
