Nov 23th, the second phase of APC (Advanced Process Control) system for the boiler unit of Anhui Huayi Chemical Co., Ltd. passed acceptance test.
The project comprises of two phases. The first phase was APC for a 1×150T/H CFBB (circulating fluidized bed boiler unit). The second phase was APC for a 2×150T/H CFBB. After accomplish, it realized the process optimization of the main-pipeline unit of the circulating fluidized bed boiler, which was a commonly acknowledged industry problem. The automatic operation rate of the project exceeded 90%. The average fluctuation range dropped by 30%. The coal consumption decreased by over 1%.
