Electrostatic precipitator system having a grid for collection of particles

An electrostatic precipitator system for dry particle precipitation comprising:

• a flue gas inlet for receiving a flow of flue gas,
• a flue gas outlet for venting the flow of flue gas,
• a flow passage extending between the flue gas inlet and the flue gas outlet, part of the flow passage being delimited by a primary collection electrode in the form of a collection plate,
• a discharge electrode connected to a high voltage generator providing for an electric field being generated around the discharge electrode, when the high voltage generator is turned on, the discharge electrode being arranged inside the part of the flow passage being delimited by the collection plate,
• a secondary collection electrode in the form of a grid being arranged within the collection plate, the grid comprising a mesh-like structure, the mesh-like structure of the grid being made of an electrically conductive material, and the grid being dimensioned, shaped and configured such that it extends along and at a distance from the collection plate, and
• an actuator configured to provide a force to the grid so as to move the grid relative to the collection plate, when the actuator is in operation.
