Abstract
Inventia se refera la un procedeu pentru lichefierea materialelor dintr-o sarja de sticla prin preîncalzirea acestora într-o zona de preîncalzire, trecerea materialelor din sarja, preîncalzite, într-o zona de lichefiere si lichefierea sarjei preîncalzite care curge pe un strat de material din sarja, stabil si suficient de înclinat pentru o deplasare libera, caldura pentru lichefiere fiind furnizata pentru combustia unui combustibil cu oxigen, în absenta efectiva a azotului, combustie ce se efectueaza pe toata suprafata înclinata a sarjei lichefiate care este într-o miscare de rotatie , caracterizat prin aceea ca, în scopul unei preîncalziri eficiente a materialului din sarja, gazele de ardere rezultate din combustia cu oxigen care are loc în zona de lichefiere sînt trecute în totalitate în zona de preîncalzire.
