在提供快速准确的流态化床模拟工具的同时,用于过程模拟器的经典零维理想反应器模型(如商业软件(如Aspen Plus®)中的模型)的主要局限性在于难以考虑每个反应器模型之间的热互易,以及将水冷壁和过热器的吸热量考虑在内,这通常被指定为模型输入,而不是由模型本身预测。这一方面对于沸腾床的几何设计和操作条件及柔性的评价尤为重要。本文提出了一种新的建模方法,通过引入一个外部模型来解决这一局限性,该外部模型以稳健的方式结合了区域方法和Aspen Plus的优点。改进后的模型具有相对较小的计算需求,因此可以可行地纳入整个电厂的动态仿真。
While providing a fast and accurate tool of simulating fluidized beds, the major limitation of classical zero-dimensional ideal reactor models used in process simulators, such as models built into commercial software (e.g. Aspen Plus®), has been the difficulties of involving thermal reciprocity between each reactor model and incorporating heat absorption by the water wall and super-heaters which is usually specified as model inputs rather than predicted by the models themselves. This aspect is of particular importance to the geometry design and evaluation of operating conditions and flexibility of fluidized beds. This paper proposes a novel modelling approach to resolve this limitation by incorporating an external model that marries the advantages of zone method and Aspen Plus in a robust manner. The improved model has a relatively modest computing demand and hence may be incorporated feasibly into dynamic simulations of a whole power plant.
