本章主要讨论MZ-Ⅲ模件组装仪表在电厂热工过程自动调节系统中的使用问题。按照汽鼓锅炉的水位、汽温、燃烧调节系统及协调控制各举一例加以说明。重点是想说明如何用MZ-Ⅲ组装仪表组成这些系统,完成热工过程自动调节中所提出的运算与调节任务,以及在组成系统时怎样解决操作、无扰切换及故障的 This chapter mainly discusses the use of MZ-Ⅲ module assembly instrumentation in power plant thermal process automatic adjustment system. In accordance with the drum boiler water level, steam temperature, combustion control system and coordinated control of a list of examples to illustrate. The key point is to explain how to use MZ-III instrument to compose these systems to complete the computing and adjustment tasks proposed in the thermal process auto-tuning and how to solve the problems of operation, disturbance-free switching and faulty
