<p>The arrangement is asymmetric relative the perpendicular centre plane (A-A) of its pressurized carrying face (16). In the arrangement a first nozzle slot (18) is placed so that the gas jet (v1) blown out of the slot follows in contact along with the curved carrying face (16) up to the area between the nozzle slots (17, 18). In the arrangement a second nozzle slot (17) is placed within the area of the edge of the curved guide face (14, R2) placed in its connection or, in the gas flow direction (v2), before said edge. The ratio of the width of the second nozzle slot (18) to the curve radius (R2) of its guide face (14) is chosen so that the gas flow is separated from the curved (R2) guide face of the second nozzle.</p> |
