Influence of Mechanical Collection on Electrostatic Precipitator Sparkover Voltage---A Laboratory Simulation

Experiments were conducted to study the effects that a mechanical collector might have on sparkover voltage in an electro-static precipitator located downstream. The test equipment for determing sparkover voltage was designed to simulate the corona wires and collector plate of an electrostatic precipitator. The flyash that was used in all sparkover tests was collected from precipitator hoppers in systems where no mechanical collector had been installed.
