The plurality of second cyclones is divided into at least a first set of second cyclones arranged about an axis, a second set of second cyclones arranged about the axis, and a third set of second cyclones, the first set of second cyclones extending about the second set of second cyclones, and the second set of second cyclones extending about the third set of second cyclones. Each second cyclone has a longitudinal axis, with the respective longitudinal axes of each of the first, second and third set of second cyclones being arranged at different angles to said axis. |
