Abstract
A first flow of gas (C) accompanying a flow of solid particles (S), is sent at supersonic speed into a first conduit (1) prolonged by a third conduit (8) and intersecting a second conduit (6) supplying a second flow of gas (G) which is deflected into the third conduit (8) to accompany the flow of particles (S) whose trajectory is not substantially modified, the flow of the first gas (C) being deflected, downstream of an oblique shockwave (13) into a fourth conduit (9) forming a separator nose (10) with the third conduit (8). The invention is particularly applicable to the injection, into a reaction chamber (16), of solid particles with a highly oxygenated gas (G) replacing an inert gas (C) for conveying the particles.
