A centrifugal separator (11) has a plurality of substantially planar walls, including a first wall (32), defining a vortex chamber (12) having an interior gas volume (31) and for establishing at least one gas vortex in the gas volume, and the gas volume has a cross section that is distinctly non-circular. In addition to conventional outlets, the separator includes a gas inlet (30) having at least one elongated jet-defining wall (40) with a free end portion (41) extending into the gas volume (31) a first distance from the first wall (32), to define a gas jet that extends substantially tangentially to the gas vortex in the gas volume. An insert (33') extends between the jet-defining wall (40) free end portion (41) and the first wall and defines a gas flow direction changing surface (47). The insert may be substantially solid refractory material, or include a number of cooling fluids circulating tubes, and a gas flow direction changing surface may be substantially planar or curved.
