Abstract
A glass fine particle synthesis burner comprising a glass raw material gas emission path for emitting glass raw material; a ring-shaped combustible gas emission path for emitting combustible gas arranged outside the glass raw material emission path; a ring-shaped combustion aiding gas emission path for emitting combustion aiding gas arranged outside the combustible gas emission path; and small diameter nozzles for emitting the combustion aiding gas within the combustible gas emission path. In a cross section of the glass fine particle synthesis burner formed by cleaving orthogonal to a central axis thereof, when the glass fine particle synthesis burner is divided into two regions by a predetermined straight line passing through a center of the glass fine particle synthesis burner, a total area of the small diameter nozzles in one of the regions is greater than a total area of the small diameter nozzles in the other region.
