摘要
This paper proposed an improved primary air (PA) control strategy for the purpose of bed-inventory balance in Circulating Fluidized Bed (CFB) boiler with pant-leg structure. An active disturbance rejection controller (ADRC) is used to estimate the bed-inventory deviation of two legs as well the internal and external disturbances, and then eliminate them by regulating the setpoints of PA flowrates of two sides in the furnace. The experiment conducted on a 600MWe CFB power plant simulation platform shows that the proposed control scheme can quickly balance the bed-inventory and decrease the overturn risk compared with traditional PI control system.
