Abstract
The DCS system is a complex integrated control system , with the development of modern major industry production which arises with the request of process control, it is the combination of the computer technology, the systems control technology, the network communication technology and the multimedia technology , the window friendly man-machine contact surface and the formidable communication function are also provided. It is a modern equipment which can complete the control process and the management process.
Expound clearly the development of the DCS， The thesis mostly introduced application of the DCS to Circulating Fluidized Bed Boiler production，I / O point of the set，and the DCS control, And system's on computer simulation run。
Keywords: DCS ; Circulating Fluidized Bed Boiler ; Control Scheme ; Configuration
