Brenner mit einem Brennerstein und Verfahren zu dessen Verwendung

摘要

The outlet consists of a block (3) of a refractory material with a passage (2) through it, made with a cylindrical outlet zone of dia. DS and length LS. The outlet zone is connected to an inlet zone (5) which is also cylindrical and has a dia. De, with the relationship of DS/De equivalent to 1.5-2.5, and the relationship Ls/(Ds-De) equivalent to 2-7. The cylindrical inlet and outlet zones are linked by a conical zone (9) with an angle of not more than 45 deg. and a length (1) which is not more than 15 percent of the outlet zone's length. The burner has at least one inner furl election channel (6), and a surrounding channel (8) for the oxygenated combustible gas.
