加热炉燃烧分散控制系统

The Distributed Control System of Combustion in Furnace

讨论了偏差比例型双交叉限幅控制系统。它的主要特点是取主温度调节器的输出值与燃料流量的测量值之差作为高、低值选择器中的一个变量因子,从而改善了控制系统的响应特性。

The dual-cross limiting control system based on deviation-ratio relation is discussed. The differ- ence between the output of the main temperature controller and fuel flow measurement is taken as the variable factor of the high and low selectors. Thus the response characteristic of the control system is improved.
