摘要
A burner-lance apparatus for burning large volumes of fluid fuels and especially adapted to fume suppression during refining of molten metals wherein a double flared passageway with a straight wall section therebetween is disposed in the nozzle for intermixing oxygen and natural gas. A tubular member for conveying oxygen terminates upstream of the passageway and natural gas is directed around the tubular member with the natural gas stream converging into the oxygen in the converging portion of the passageway. The intermixed gases pass through the straight wall section and then expand in the second flared or divergent passageway.
