The paper discusses pulse energization in the tuft corona regime of negative corona. Fabric filtration, with integral particle charging and collection in a combined electric and flow field, is sensitive to maldistribution of current among bags energized by one power source, especially when operating in the tuft corona regime below glow corona onset. Pulse energization superimposed on the direct current (DC) applied to the bags tends to equalize the currents. The currents are also equalized by misalignment. However, the misalignment could cause sparking at lower applied voltages. Pulse energization in the tuft corona regime could also be useful in electrostatic precipitators (ESPs) if misalignment is mild.
