| Abstract: | The basic concepts concerning parametric identification and neural networks is being elucidated;with NO_x emission conditions of a power plant's 600MW boiler as the object of study,a large amount of data concerning the boiler's operational parameters,NO_x emission and boiler efficiency have been recorded,with which relevant mathematical models are set up and,applying identification methods by artificial neural networks,the quantitative relationship between NO_x emission and operational parameters and boiler efficiency as well are obtained.Herewith a facile way of raising the boiler's operational profitability,optimizing control and reducing NO_x emission has been provided.Figs 6,tables 2 and refs 3. |
