Abstract: Located at the bottom edge of the outflow orifice (6) of a steam distributor is a nozzle (10) which extends in the manner of a slit over practically the entire length of the outflow orifice (6). The edges (14, 15) limiting the nozzle orifice (13) laterally are acute-angled and sharp; the inner walls (18, 19) adjoining these edges are designed so that water droplets which possibly form are conveyed away downwards.Because of the sharp edge design, water droplets cannot form in the outflow region (13) of the nozzle. The outflowing steam which subsequently mixes with an air stream (5) is therefore free of water drops. The formation of water droplets on the inner walls (18, 19) adjoining the said edges is harmless, since these droplets are conveyed away downwards as a result of the inclination of the said walls.

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.

Abstract: A cyclone with a tangential peripheral inlet and a central axial outlet is improved as to efficiency by inducting air between the inlet and the outlet. The inducted air is diverted by a baffle that temporarily separates it from the dust-laden inlet air, the baffle being arcuate in the same direction as the wall of the separation chamber, so that the inducted relatively dust-free air forms an inner layer and the dust-laden air forms an outer layer in the separation chamber. This promotes the separation of the dust on the inner side of the outer wall of the chamber and so facilitates separation of the dust from the air. A portion of the outlet air from which the dust has been separated can also be recycled in a stream disposed on the other side of the inducted ambient air.

The flow of the particle containing gas into the nozzle is confined by a flow of clean, particle free gas, as between a core and a sheath thereof, such that the particles have the same position at the inlet of the nozzle or at some location downstream of the inlet, such as the exit of the nozzle, thereby allowing only those particles containing the trajectory corresponding to the selected particle properties to be transmitted through one or more collimator holes or skimmers which are disposed a sufficient distance from the nozzle exit. The particle properties which determine their trajectory are particle mass and dimensions.

The air inlet is placed in a plane substantially parallel to the surface of the deflector over which air flows during vehicle movement and opens normally to the direction of the air flow.
