Abstract
Provided is a glass particulate deposit manufacturing method for manufacturing a glass particulate deposit comprising mounting a fixing jig on an outer periphery of an outermost pipe of a burner; inserting a burner cover from a tip end of the outermost pipe of the burner; and sandwiching and compressing a part of the fixing jig between the burner cover and the outermost pipe of the burner to fix the burner cover to the burner, wherein an outer diameter of a part of the fixing jig that is not compressed is greater than an inner diameter of a part of the burner cover inserted to the tip end of the outermost pipe of the burner.
Claims11
A manufacturing method for a glass particulate deposit comprising mounting a starting rod and a burner in a reaction vessel;
- introducing a glass raw material to the burner;
- subjecting the glass raw material to a flame hydrolysis reaction to generate glass particulates in flame formed by the burner;
- and depositing the generated glass particulates on the starting rod to manufacture a glass particulate deposit, wherein
- the manufacturing method comprises:
- mounting a fixing jig on an outer periphery of an outermost pipe of the burner;
- inserting a burner cover from a tip end of the outermost pipe of the burner;
- and
- sandwiching and compressing a part of the fixing jig between the burner cover and the outermost pipe of the burner to fix the burner cover to the burner, and
- an outer diameter of a part of the fixing jig that is not compressed is greater than an inner diameter of a part of the burner cover inserted to the tip end of the outermost pipe of the burner.
A burner comprising:
- a multi-pipe burner;
- a burner cover;
- and
- a fixing jig mounted on an outer periphery of an outermost pipe of the multi-pipe burner, a part of the fixing jig being sandwiched and compressed between the burner cover and the multi-pipe burner to fix the burner cover to the multi-pipe burner, wherein
- an outer diameter of a part of the fixing jig that is not compressed is greater than an inner diameter of a part of the burner cover.
