Modified graphical autocatalytic set model of combustion process in circulating fluidized bed boiler

China's coal-dominated energy structure will not change in a short time. In order to implement the relevant national policies on energy conservation and emission reduction, it is a good response to adopt circulating fluidized bed boilers in coal-fired power stations. Circulating fluidized bed boiler adopts fluidized combustion, which has high reliability and high utilization rate because of its special combustion mode and particle recycling device. For the low calorific value inferior fuel which is difficult to burn in common boiler, CFB boiler also has certain adaptability and compatibility. In this background, this article with coal gangue as the representative of the inferior coal are discussed its application in the circulating fluidized bed boiler, the combustion process, boiler equipment and special fly ash produced by combustion is proposed that often appear in the three aspects of problems, and accordingly put forward the solution and optimization measures, provides reference for the actual process.

Circulating Fluidized Bed Boiler is a complicated control object with big delay, multi-variable and strong coupling, especially the combustion in it. It is too difficult to build an exact mathematic model to describe the combustion process. And it is hard to get ideal control effect with normal controller. This paper presents the overview of advanced control techniques in thermal process control of Circulating Fluidized Bed Boiler, such as decoupling control, predictive control and fuzzy control. The future of advanced control research and application is also discussed.
