摘　　要：主要论述了热水锅炉控制在供热系统调节中的作用及其重要意义,并根据气象条件及供暖区的不同特点提出了可应用于不同情况的链条式热水锅炉控制方案。研究了链条式锅炉存在的控制难点,给出了一种锅炉供水温度的设定方法,提出了适用于时滞、非线性系统的带预测模型的神经网络PID控制,并将其应用在锅炉燃烧系统中,保证热水锅炉的安全经济运行。The function and important significance of hot water boiler in heating system is discussed. Fur- ther more, a control blue print of chain grate stroke hot water boiler, which can be applied in different situations, is put forward, according to the weather conditions and different characteristics of the heating areas. The difficulties in boiler control are studied, a method to establish the temperature of supply-water is given, and a kind of neural network PID control with predictive model is put forward, which fits the nonlinear system with time lag and is applied in boiler combustion control system to guarantee the boiler＇s economic and safe running.
