摘要
介绍了一种利用经典热量信号建立锅炉有效吸热量模型的方法。引入凝结比例系数,简化了汽包液面下汽容积的求取。建立一个300MW自然循环锅炉汽包水位动态模型,通过仿真验证能较好的反映汽包水位动态变化。
The model of heat released from boiler combustion is established by the classical heat signal method. A condensation ratio coefficient is introduced to obtain the steam volume under water level in the drum. A model of drum level dynamics in 300MW natural circulation boilers is presented. Simulation results show that the output fits well with the practical drum level dynamics.
