  • alumina 1714 alumina 1714
  • CPB&NPB 1715 and TM 1713 cells a window 1711 with collimator matrix 1712 (eg. silicon nitride or pure silicon is suitable too, and aluminum respectively).

  • the device 1803 converts heat energy of waste flux 1805 (i.e. hot gases, steams and/or liquids, where 1806 is an input) into a photon beam that is directed back to waste flux, and has a fine-tune to a specific energy of molecular bonds and atom-bond electrons. Photochemical degradation of a specific molecular and/or intra-atomic bonds creates conditions for a new bonding and chemical reactions, as required. As mentioned above, a fine-tune to a specific energy depends on Z target and characteristics of collimator matrix that defined on pre-design stage.
  • ULSICs plasma generator 1900 has a sealed housing and depending on the application it can be used in various corrosive environments 1904 (hot gases/plasma) and under different pressures, see Figure 19. Installation of the device is carried out by means of adhesive and/or a special clip-clamping 1901 that does not violate the integrity of the surface to which the device is attached to (a wall 1902).

Abstract

La présente invention concerne un procédé d'obtention d'un plasma dans un caloporteur pour la stabilisation de la combustion et la neutralisation de produits toxiques et un dispositif associé. Selon le procédé, une partie de l'énergie thermique du caloporteur est convertie en une impulsion de faisceau de particules (CPB&NPB), ledit faisceau de particules est accéléré, polarisé, focalisé et dévié de nouveau vers la zone du caloporteur.
