A gas delivery system provides a first gas (14) which is in a liquid state under extreme pressure and in a gaseous state under intermediate pressure. A particle delivery system provides a slurry (22, 24) comprising the first gas (14) in a liquid state and a second gas (18) in a solid state. The second gas (18) is selected so that it will solidify at a temperature at or above the temperature of the first gas (14) in a liquid state. A nozzle assembly (12) connected to the gas delivery system and to the particle delivery system produces a stream (20) having a high velocity central jet comprising the slurry (22, 24), a liquid sheath surrounding the central jet comprising the first gas (14) in a liquid state and an outer jacket (26) surrounding the liquid sheath comprising the first gas (14) in a gas state.
Un dispositif de distribution de gaz fournit un premier gaz (14), à l'état liquide sous une pression extrême et à l'état gazeux sous une pression intermédiaire. Un dispositif de distribution de particules fournit une pâte épaisse (22, 24) constituée du premier gaz (14) à l'état liquide et d'un second gaz (18) à l'état solide. Ce dernier (18) a été choisi pour son aptitude à se solidifier à une température égale ou supérieure à celle du premier gaz (14) à l'état liquide. Un ensemble tuyère (12) relié aux dispositifs de distribution de gaz et de particules génère un courant (20) constitué d'un jet central, propulsant à une vitesse élevée la pâte épaisse (22, 24), d'un fourreau liquide, entourant le jet central, faite du premier gaz (14) à l'état liquide et d'une enveloppe extérieure (26) entourant le fourreau liquide et comprenant le premier gaz (14) à l'état gazeux.
