通过研究循环流化床锅炉燃烧系统的机理和非参数建模方法，基于对循环流化态燃烧机理的认知，给出模型辨识的数据选择标准；挖掘机组运行的历史数据，提出了利用群体智能寻优算法进行燃料量与床温之间传递函数的参数辨识方法，并给出了快速仿真的公式以及一类单输入单输出系统的辨识结果和验证方法。所建立的传递函数模型完全能够表征具体某台循环流化床锅炉热工特性，为后续的控制逻辑和控制器的优化提供了数学依据。

This paper summarized two methods which include mechanism and non-parametric modeling in the cir-culating fluidized bed ( CFB) boiler's combustion system. Based on the understanding of combustion principle of circulating fluidized state, the criterion of data selection was given. By mining the historical datas of unit operation, a method of identifying undetermined parameters of the transfer function between fuel and bed temperature using the swarm intelligence optimizing algorithms was presented. Then, the rapid simulation formulas of thermal process and identification result and validation method of a class of single-input single-output system were given. Transfer func-tion which was established by this method can entirely represent the thermal characteristics of CFB boiler and pro-vide a mathematical basis for subsequent control logic or parameter's optimization of controller.
