DEVICE AND METHOD FOR DIAGNOSIS OF CAUSE OF UNBALANCE

摘要

PROBLEM TO BE SOLVED: To provide a device and method for diagnosis of cause of unbalance capable of easily diagnosing a cause of generation of O₂ unbalance in detail when O₂ unbalance in a gas flow at an outlet of an ECO (carbon economizer) is generated.;SOLUTION: The unbalance cause diagnosis device 10 includes a corresponding burner DB 32 in which O₂ concentration measuring points 610 in the gas flow at the outlet of the ECO are associated with positions of burners 110. The device includes: receiving a malfunctional warning from an unbalance monitoring device 41 and also receiving distribution data of O₂ concentration; extracting the O₂concentration measuring point 610 of the data indicating malfunction in the received distribution data of O₂concentration; specifying the position of the burner 110 corresponding to the extracted O₂ concentration measuring point 610 based on the corresponding burner DB 32; receiving oil pressure data of the burner 110 at the specified position; and diagnosing that the relevant burner 110 malfunctions when an oil pressure difference between the received burner oil-pressure data and an oil pressure data of the relevant burner memorized in a burner oil-pressure DB (database) 31 is equal to or more than a predetermined value.;COPYRIGHT: (C)2012,JPO&INPIT
