A separator for separating particles carried in a fluid carrying medium is disclosed. The separator includes an elongated duct and associated openings incorporated in a solid body. The duct is axisymmetrical relative to its longitudinal axis, and includes a curved wall portion having a curved cross-section taken along the longitudinal axis. An axisymmetrical opening located downstream of the curved wall portion leads from the duct into an axisymmetrical channel which is substantially radially disposed relative to the longitudinal axis. Continuation of the duct downstream of the opening is a discharge portion which is substantially colinear with the longitudinal axis. In operation, a substantial majority of the fluid carrying medium leaves the duct radially through the opening and channel in a state substantially free of particles. A remaining small portion of the fluid carrying medium and a substantial majority of the particles are channelled into the discharge portion by centrifugal forces arising due to travel of the particles along the curved walls. For industrial scale separation of particles from a fluid carrying medium, such as for the clean-up of stack gases, an array of several hundred to several thousand of the separators is provided.

A separator adapted for separating particulate matter carried in a carrier gas, from the carrier gas, the separator comprising: a solid body incorporating an opening leading into a duct having a substantially straight longitudinal axis, adjacent to the opening the duct having walls defining a nozzle axisymmetrically arranged relative to the longitudinal axis of the duct, the nozzle walls positioned at an angle ab2, and terminating in a second opening in the body, the angle b90°and the sum of the angles abqq120°to 180°, R is approximately between 0.04 to 0.20 inches, and D2/D* is approximately between 1.085 to 1.52, whereby the gas and particulate matter are subjected to a certrifugal force by the walls of the curved portion and the channel which carries the majority of the particulate matter to flow along the longitudinal axis and into the outlet portion together with an appropriate amount of carrier gas.
