Most
electrostatic precipitators are operated dry and use rappers to remove the collected
particulate matter. The term dry is used because particles are charged
and collected in a dry state and are removed by rapping as opposed to water
washing which is used with wet ESPs. The major portion of this course covers
dry ESPs that are used for collecting dust from many industries including steel
furnaces, cement kilns and fossil-fuel-fired boilers
