If exhaust gases are to be cleaned from particulate matter at high flow rates and, simultaneously, at low pressure drops, an electrostatic precipitator (ESP) is a suitable device. ESPs are widely used for removal of fly-ash in coal fired power plants commonly operating at moderate temperatures up to about 200°C and ambient pressure. Today, particle collection at high temperatures and/or high pressures is of current interest because of new concepts for electrical power generation systems. However, the capabilities of electrical precipitators under these extreme conditions are only poorly investigated. Therefore, the paper works out the fundamentals of high-temperature and/or high-pressure electrostatic precipitation. It provides a basis for discussion and gives the interested reader several tools to permit estimating the potential for electrostatic precipitators under extreme conditions.
