Abstract
An electrostatic precipitator especially useful in separation of particulate matter from gas streams under high pressure and high temperature conditions has a collection electrode that is formed of a porous material and means to effect a flow of gas from the clean side of the electrode, through the porous electrode, to dislodge solids collected on the electrode for cleaning purposes. A chamber is formed on the clean side of the collecting electrode and a jet pulse of gas is charged to the chamber, which pulse of gas is distributed through the porous collecting electrode to dislodge the solids from the collecting surface thereof. In one embodiment, a porous flexible member is disposed adjacent the collecting surface of the collecting electrode and the solids are deposited thereon and dislodged therefrom by passage of a gas through the porous collecting electrode.
