Abstract Aiming at the difficulties in selecting instrument and control (I&C) system equipments in supercritical circulating fluidized bed boiler (CFB) unit,type selection of pressure measuring instrument,temperature measuring instrument,instrument control cable and flue gas analyzer are analized based on the characteristics of CFB boiler in this article,and type selection recommendation is gaven based on the engineering experience of the same type CFB units the author participated in. At the same time,an anti-blocking pressure sampling device is proposed for supercritical CFB units .
