Enhancing precipitation efficiency using conventional and fuzzy logic control. Modern high-voltage (HV) power supplies based on fast switching devices such as insulated-gate bipolar transistors (IGBTs) increases the performance of the corona power of electrostatic precipitators (ESPs), resulting in improved gas cleaning and higher performance of the ESP. Unfortunately, increased energy consumption of the precipitator requires a higher amount of electricity to be generated the power station, which results in higher CO2 emissions, With both centralized and decentralized control algorithms, the total energy consumption of an ESP can be significantly reduced while achieving low dust-emission values. The control system operates with a few input signals only and has been linked and extended to the plate-rapping system. Power savings depend on the operating conditions, and experiments have shown an average savings in the range of 30-60% within a longer period of operation.
