Abstract
A cause estimation system includes a training data acquisition unit that acquires training data in which sensing data is used as an explanatory variable and a flame failure detection cause is used as an objective variable, the sensing data being sensed by a combustion system during a predetermined time period preceding a time when a flame failure is detected based on a flame voltage indicating a main burner's flame state. The cause estimation system further includes a machine learning unit that performs machine learning based on the training data acquired and that constructs an estimation model in which a learning result is reflected, and a cause estimation unit that inputs sensing data sensed by the combustion system during a predetermined time period preceding a new flame failure detection timing into the estimation model and that acquires a new flame failure detection cause output from the estimation model.
