ＤＥＢ协调控制系统中，锅炉热量信号和锅炉指令信号是２个关键信号。通过对锅炉热量信号的实现及影响因素的分析和锅炉指令运算限制逻辑的设计，找到目前运算控制逻辑调试中和应用时存在的问题。因此，加强锅炉指令限制逻辑的调试、维护、管理对机组的安全、稳定运行是非常重要的。
DEB coordinated control system, the boiler heat signal and the boiler command signal are two key signals. Through the realization of the boiler heat signal and the analysis of the influencing factors and the design of the logic limit calculation of the boiler instruction, the existing problems in the logic control of the operation control and application are found out. Therefore, it is very important to strengthen the commissioning, maintenance and management of the logic command of the boiler to keep the unit safe and stable.
