摘　　要：把常规ＰＩＤ控制法与优化算法有机地结合起来，在保证压力较稳定的前提下，应用优化算法寻找最佳风煤比，使系统不断向最优工作点靠近，提高了热效率，从而达到节煤的效果．其次，由于对最佳风煤比寻找是一个连续不断的过程，所以算法可以适应由于煤质变化或工况变化等引起的最佳工作点的漂移，具有较好的实用性．Under the prerequisite of ensuring stable pressure,the combustion system of boiler is made to continuously near optimum operating point by combining PID control method with optimization method,and finally a optimal wind coal ratio can be sought.When the system runs in the optimal wind coal ratio,its heat efficency can be increased,so coal can be saved.Since the process of optimum is continuous,the method can adapt to the drift of optimal operating point caused by the change of the property of coal or the change of work conditions of the system.
