| Abstract: | In order to realize the optimum combustion of the fluicized bed boiler, a control scheme(named three layered fuzzy clntrol ring) has been put forward to improve the efficiency of the boiler. It is according to the charactor of the boiler's combustion, and ained to control the combustion efficiency indirectly, through searching the best air coal ratio. The main regulating parameter is the tempreture of the fumace tank, the decondary regulating parameter is the tempreture of the emission. By using to the change step self optimization fuzzy control and the self regulation of control on line, the satisfied effect has been proved by the practice. |
