【摘要】 为进一步简化循环流化床锅炉燃烧系统机理模型,解决模型求解中的刚性问题。本文在分析碳燃烧速率常数与循环流化床锅炉燃烧系统中过程变量的关系的基础上,应用偏最小二乘法(PLS)建立了碳燃烧速率常数的软测量模型;并采用工业数据对基于复杂机理模型和软测量模型的碳燃烧速率常数进行仿真研究;仿真结果表明本文所建立的软测量模型可以满足模型的精度要求。更多还原

【Abstract】 To simplify the model of CFB Boiler combustion system and deal with the stiffness problem in this model-solving, a soft sensor model of carbon combustion rate constants is built by applying PLS identification algorithm, based on the relationship of the carbon combustion rate constants and the process variable of the combustion process. The results of simulation of the soft sensor model and complex mechanism model of the carbon combustion rate constant indicate that the soft sensor model based on PLS would be effective.更多还原
