| 摘 要： | 运用集总参数法建立炉膛的动态数学模型。应用前人提出的燃烧稳定性评价指数,该指数以燃烧过程能够克服的最大的燃料量的扰动来定量。通过仿真求出不同燃烧工况下对应的CSI值,以此作为评价燃烧稳定性的基准值,将实测的燃烧工况的CSI值与基准值相比较,据此对燃烧过程的稳定性做出评价。运行人员应以燃烧稳定性基准值为燃烧调整的目标,优化燃烧过程。

| Abstract: | Thispaper establishes a dynamic mathematical modeland adopts anew combustion stability index (CSI) for utility coal-fired boilers. CSI is measured by the maximum disturbance ratio of fuel mass flow rate which can be overcome by the stable combustion process. Via simulation we can get corresponding CSI index according to differentcombustionstate, which is takenasthe basement. The CSI index of practical combustion stateiscompared with the basement. Based on the method we can evaluate the stability of combustion state. |
