| Along with the development of the high parameter and large capacity of the boiler,it is essential that use the automatic control system in the water supply system. It may reduce the operator's labor intensity and ensure boiler safely running. Regarding the boiler of large capacity and high parameter,the water supply system is extremely complex and perfect.The supercritical boiler will be the future national tendency,and the water supply system is an important link.The strategy of the supercritical boiler's feed water control is introduced,mainly including the feed water flow control loop, water supply instruction forming loop,and consist of subsidiary loop's control strategy as well.The configuration which is introduced has already succeeded in commercial operation at Hubei Jingmen the 3rd period 2×600MW fossil fuel plant. It's hoped that the analysis given during the text can provide useful experience and lessons for the design of the supercritical boiler's feed water control to some extent. |
