摘要:
以某循环流化床富氧燃烧中试系统为模拟对象,借助Aspen Plus流程模拟软件搭建了Oxy-CFB燃烧系统的稳态模型.在此基础上针对动态过程模拟进行改进,并利用Aspen Dynamics平台建立了该燃烧系统的动态模型,利用试验数据对模拟结果进行了验证.基于动态模型对Oxy-CFB床温以及燃烧排放产物中二氧化碳、氧气、一氧化碳、一氧化氮等进行了仿真研究.研究表明,基于Aspen平台的动态过程模拟为Oxy-CFB锅炉燃烧系统的动态特性分析提供了新的研究手段,模拟所得的床温及烟气各组分随给煤量、一次风量阶跃变化的动态响应规律可为今后Oxy-CFB燃烧系统的控制设计提供重要依据.
Abstract:
Taking an oxy-fuel circulating fluidized bed(Oxy-CFB)combustor pilot facility as the simulation object, a steady-state model for the Oxy-CFB combustion system was built with the platform of Aspen Plus. After modifying the steady-state model for the dynamic process simulation, a new dynamic model for the combustion system was built based on Aspen Dynamics and the results were validated by the test data. The simulation study on the responses of the bed temperature and the components, including carbon dioxide, oxygen, carbon monoxide, and nitrogen monoxide in the flue gas, was carried out. The research results show that the dynamic model based on Aspen provides a new method to investigate the dynamic characteristics of the Oxy-CFB combustion system. The dynamic response characteristics of bed temperature and gas components for the coal feed and primary air step changes can provide valuable information for design and implementation of the control system of the Oxy-CFB combustion system.
