Estimating the term…
The present invention relates to a process for forming a vitreous layer on a refractory surface, in which a vitrifying agent is projected by means of an apparatus against the said surface with an oxygen-containing carrier gas and simultaneously with a combustible gas, the latter generating a combustion flame, characterized in that the vitrifying agent comprises particles of cullet and in that the flame generated provides, at least partially, the heat needed to form the vitreous layer on the surface. The vitreous layer thus formed makes it possible to prevent the build-up, on the refractory walls of high-temperature ovens, of dust or by-products coming from the raw materials and/or their reaction products.
