Abstract

"PROCESSO PARA ESTABELECER MúLTIPLOS JATOS DE GáS COERENTES A PARTIR DE UMA úNICA LANçA, E, LANçA PARA ESTABELECER MúLTIPLOS JATOS DE GáS COERENTES". Um sistema para estabelecer uma pluralidade de jatos de gás coerentes próximos um do outro, usando uma única lança, no qual uma pluralidade de jatos de gás é ejetada de uma correspondente pluralidade de bicos em uma lança e um envoltório de chama é estabelecido ao redor da pluralidade de jatos de gás, e os jatos permanecem distintos e não coalescem ao longo de suas extensões.
