1. A cyclone separator arrangement, comprising:
a preceding apparatus having an outlet, and
a cyclone separator having an inlet, the arrangement further comprising
a crossover duct connected to the outlet and the inlet for supplying gas flow comprising particles from the preceding apparatus to the cyclone separator, wherein
the crossover duct creates a flow channel from the outlet to the inlet, the horizontal cross-section of the preceding apparatus has a round shape having a horizontal inner diameter (D), and
wherein
the width (d) is a dimension of the flow channel in a horizontal plane crossing the centre of gravity (CF) of a flow-through area of the flow channel at the outlet of the preceding apparatus,
wherein
the inner diameter (D) is a width of the preceding apparatus in a horizontal plane crossing the centre of gravity (CP) of a flow-through area of the preceding apparatus and being parallel to the width (d) of the flow channel, and that
the flow channel is arranged asymmetrically in a horizontal cross-section of the preceding apparatus,
wherein
the flow channel having a cross-section having a height (H) and a width (d), said width (d) relating to the inner diameter (D) such that 0.15×D<d<0.6×D, in that
the crossover duct is arranged to the round preceding apparatus so that a distal wall of the crossover duct is tangentially directed in respect of the preceding apparatus, and in that
a relation of the height (H) of the crossover duct to the width (d) thereof is H/d<3.75 at the outlet.
