Title:
OPERATION CONTROL SYSTEM OF CIRCULATING FLUIDIZED BED BOILER
Document Type and Number:
WIPO Patent Application WO/2013/172052
Kind Code:
A1
Abstract:
Provided is an operation control system of a circulating fluidized bed boiler capable of control for optimizing multiple index items of the circulating fluidized bed boiler by means of multiple setting items. This operation control system is provided with: a boiler controller (27) which performs operations of the boiler (2) with an operation amount (MV) determined on the basis of comparison between the input values (SV3) of the setting items and the measured values of the index items; a Bayesian network inference unit (39) which selects some of the setting items and calculates adjustment values (SV2) for adjusting the input values (SV1) of selected setting items that have been selected; and an input value adjustment unit (51) which passes adjusted input values to the boiler controller (27) as input values (SV3) of the selected setting items, said adjusted input values being a function of the adjustment values (SV2) and the operator input values (SV1) inputted by the operator. The Bayesian network inference unit (39) calculates the aforementioned adjustment values (SV2) by performing operations using a Bayesian network.
