摘要

PROBLEM TO BE SOLVED: To provide a method of easily evaluating a burner for manufacturing quartz glass having excellent optical characteristics with good accuracy, a method of manufacturing the burner for manufacturing the quartz glass, a burner for manufacturing the quartz glass, a method of manufacturing the quartz glass and quartz glass. SOLUTION: The method of evaluating the burner 1 for manufacturing the quartz glass is a method of evaluating the burner for manufacturing the quartz glass used in manufacturing the quartz glass by gushing raw materials and combustion gases from the front ends of a plurality of tubes, in which the gases are gushed from the respective tubes and the arranging states of the respective tubes are evaluated by detecting whether the flow of the gases flowing out to the respective tubes is free of disturbance and is even or not.
