The oxygen/fuel burner according to the invention with a variable flame length and having a burner body (2) with at least one oxidizing-agent feed (3) and a fuel feed (4), which is accommodated by the oxidizing-agent feed (3) and can be displaced axially into a mixing and combustion chamber (5) of a burner block (1). The burner, which is operated with a momentum flux density ratio of oxidizing agent/fuel of from 0.0015 to 28 and with an oxidizing agent with a swirl number of up to 3, can be used in an operationally reliable and inexpensive way in any conventional furnace installation, but in particular in melting furnaces, particularly advantageously in glass-melting furnaces. |
