PROBLEM TO BE SOLVED: To provide an operation diagnostic method of a circulating fluidized bed boiler for supplying necessary settings for simultaneously satisfying target values of multiple index items without requiring determination of an experienced operator.SOLUTION: An operation diagnostic method of a circulating fluidized bed boiler includes: an inferred data calculation step S4 for inferring a degree of influences exerted by setting items on index items and for inferring target values of the setting items for satisfying the target values of the index items; an ordering step S5a for ordering the setting items on a basis of the degree of influences exerted by the setting items on the index items; and an output step S6 for outputting information for controlling the index items to the target values. In the inferred data calculation step S4, the target values of the index items are input into a Bayesian network to calculate probability values which are the degree of influences exerted by the setting items on the index items. In the ordering step S5a, the probability values are used to order the setting items. |
