PROBLEM TO BE SOLVED: To provide a combustion abnormality prediction device capable of predicting an abnormality suitably by constructing a machine learning model (program) using an operator's abnormality judgment as teacher data, a combustion abnormality prediction program, and a combustion control system including them. A combustion abnormality predictor predicts a combustion abnormality generated by an intelligent information processing technique by using learning data including at least a state quantity related to a combustion furnace and teacher data including at least manual intervention data of an operator. The abnormality prediction program is used to predict whether or not the state quantity related to the combustion furnace is abnormal, and the predicted result is output. [Selection diagram] Fig. 1
