| Abstract: | Based on the analysis of variable-frequency energy-saving principles for the centrifugal fans,the pressure-flow features and the efficiency features in case of air-damper control and variable-speed control,the nature of frequency control for energy saving was presented to improve the operation efficiency of fans.Besides,the analyzing and calculation method for energy saving by means of inverter retrofit was proposed on the basis of efficiency of fans.Taking the test and statistical data in HV inverter retrofit in Texwinca Thermal Power Plant for instant,the validity and accuracy of this calculation method were verified.The results show that it provides useful reference for the economic analysis and decision of HV inverter retrofit projects. |
| Keywords: | HV inverter boiler fans energy-saving retrofit |
