Apparatus for producing glass particles deposit

摘要

In an apparatus for producing glass particles deposit according to the present invention, a plurality of glass particle synthesis burners are placed on a front face of a reaction vessel, and at least one exhaust port is provided on a rear face of the reaction vessel. Two wall faces extending from both sides of the exhaust port and being in contact with two side faces of the reaction vessel are provided so that its contained angle is 90 degrees or less. Assuming that the shorter distance between the shortest distance from a rotation axis of a target rod to the side face of the reaction vessel and the shortest distance from the rotation axis of the target rod to the wall face is L, and the outer diameter of the glass particles deposit deposited on the target rod is d, L is greater than d.
