Abstract
An oxygen-fuel burner is disclosed which has a wide range of operation, allowing turn-down ratios of 5 to 1. In addition, the burner construction, which is not liquid cooled, maintains an acceptable burner tip temperature by having a tip which extends outwardly beyond the nose portion of the burner such that the oxygen flows columnarly therealong and functions to remove heat from the tip. In addition a delayed combustion is obtained by the gas discharge tip being axially spaced apart from the oxygen discharge orifice. The burner produces sufficient heat to permit the melting of batch materials to produce molten glass without the use of regenerators or recuperators.
