Claim 0:
1. A method for fabrication of a glass preform, the method comprising:
production of soot particles in a combustion chamber using a precursor material, wherein the soot particles are produced by heating the precursor material with facilitation of a plurality of burners, wherein the heating of the precursor material produces the soot particles along with one or more impurities, wherein the combustion chamber comprises the plurality of burners and an inlet, wherein the combustion chamber is filled with a purging gas, wherein the inlet is used for insertion of the purging gas in the combustion chamber, and wherein the combustion chamber is made of hastelloy material;
agglomeration of the soot particles, wherein the agglomeration is performed inside a plurality of agglomerator tubes;
separation of the soot particles from the one or more impurities, wherein the separation of the soot particles is performed in a cyclone separator;
collection of the soot particles, wherein the collection of the soot particles is performed in a soot collection chamber; and
compaction of the soot particles, wherein the soot particles are compacted with facilitation of a preform compaction chamber, wherein the compaction of the soot particles is performed with continuous facilitation of a dehydration gas, and wherein the dehydration gas is chlorine;
sintering of the compacted soot particles, wherein the compaction of the soot particles followed by the sintering results in formation of the glass preform.
