GE’s electrostatic precipitator integrated controller (EPIC) is an ESP bus-section controller for transformer rectifier sets (T/Rs), which includes basic functionalities, energy savings, current control, spark detection, and rapping efficiency. It uses software algorithms like electrostatic precipitator optimizing of charge (EPOQ) and opacity optimization (OpOpt) to obtain optimum performance from the ESP.
With EPIC well below 20mg/Nm3 particulate emissions can be achieved.
