In accordance with the control demands of SCR flue gas denitrification systems in fossil fired power plant and its current design status, the strategy using fieldbus to replace the distributed control system is proposed. With Profibus as example, specific methods for model selection of local instruments, system connection and network segment division, etc. , in construction of SCR flue gas denitrification fieldbus network are described, and combining practical engineering, detail system configuration is given. The analysis indicates that application of fieldbus technology in SCR flue gas denitrification system is feasible;it can fully play the superiority of integrating management and control, and saving cables, thus it is worth to be promoted in applications.
