基于动态过程模拟的Oxy-CFB锅炉燃烧排放特性研究

Using the Aspen Plus, the paper firstly built a steady-state simulation model for an oxy-fuel circulating fluidized bed combustor pilot facility. After modifying the steady-state model for the dynamic process simulation, a new dynamic model was built based on Aspen Dynamics. The study of dynamic characteristics focused on the reponses of the components such as carbon dioxide, oxygen, carbon monoxide, and nitrogen monoxide in the flue gas for the coal feed and primary air step changes was carried. The research results show that the dynamic model based on Aspen Dyanmics provides a new method for the dynamic characteristics research.
