Abstract: A new apporach in improving traditional methods of control is presented. The paper tries to collect relevant expert knowledge and experiences of operators, and puts forward an intelligent control scheme. To compensate for the disadvantages in traditional control methods in their inability to adapt to the wide fluctuations in boiler load, it comes up with a rule based expert control method. To obviate difficulties in finding an optimum control, it presents a simple but practical method of steady wind to coal balance based on experiences. The method has been applied in actual cases, showing that it is practical. It increased the efficiency of combustion, comparing better than traditional control methods.
