Abstract For the purpose of automatic monitoring of the boiler combustion stability and quantifying the degree of combustion stability, a determination model for the combustion stability based on BP neural network is proposed. This model, according to the digital image processing technology, captures flame combustion state images, then extracts combustion states. Aimed at shortcomings of BP algorithm – anti-jamming ability, slow learning rate, easy to fall into local minimum, etc., this paper proposes a BP algorithm based on hierarchical dynamic adjustment of different learning rates. The samples are divided into training samples and test samples for training and testing the established model. Experience has shown that the improved model not only has better fault-tolerance and mapping ability but also improves recognition rates and computing speed, which can meet the real-time requirement of stability determination.
