Abstract: The application effects of the “System Optimization Analysis Program” in 300MW boiler with ‘W’shape flame were analyzed. Under the conditions of 100%ECR (economical continuous rating), 90%ECR, 83%ECR, 75%ECR and 53%ECR (peak shaving minimum load), the optimization experiments of the boiler performance were carried out, and the optimized operation curves of various loads were obtained. The optimized results shows that the optimization direction is correct; and it can be used as reference for the operation optimization of boilers No.2, No.3, No.4 and other boilers with the same combustion mode. 

Key words: boiler with ‘W’-shaped flame, optimization of boiler performance, artificial intelligent neural network, mathematical model, application and analysis
