Abstract


The circulating fluidized bed boiler is the development of burn coal generating set nowadays , is also the environmental protection project of the country. With petroleum resource exhausted gradually, the circulating fluidized bed boiler choosing equipment as the clean fire coal head will also can not stop working within very long time, although the domestic CFB boiler fabrication technology is gradually perfect, but complicated process having characteristic property such as nonlinearity , large time delay, multi-coupling, every factory use coal source and use coal quality are different, result in CFB boiler combustion process auto control and online optimization are very difficult. For realization systematic fine of nonlinearity, large time delay controls, design an application software support from Marsik and Strejc’s identification-free adaptive control algorithm and Qingyin jiang’s identification-free adaptive predictive control algorithm, applying it to the circulating fluidized bed boiler controls, achieve good results.
