Properties of RE-W cathode and its application in electrostatic precipitation for high temperature gas clean-up

► Three RE-W electrostatic precipitation cathodes were prepared. ► RE-W cathode electron emission properties were examined and analyzed. ► Y-W cathode shows the best emission properties at atmosphere pressure. ► Collection performance of a high temperature Y-W cathode ESP was investigated. ► Higher resistivity particles tend to be collected effectively at high temperature.
