Study On Online Judgement System Of Boiler Combustion Stability And Operating Economy

On the base of the study of combustion characteristics of large capacity coal-fired boiler, a fuzzy comprehensive judgement model of boiler combustion stability is established. The methods of fuzzy mathematics and neural network are applied to establish the judgement model with self-studying function. This model takes the influence of ten key factors to the combustion stability into seriously consideration, and especially realizes self-studying of each factor with neural network. On the other hand, the method of multivariate linear regression analysis is used to deduce the relevant matrix between element analysis and of industry analysis coal. Then a new calculation model of boiler efficiency by use of industry analysis data is established. Finally, A online judgement system of boiler combustion stability and operating economy is developed and realized on a 200MW power station in HeBei Province.Li Jingtao(Engineering Thermalphysics)Directed by prof.
