<p>The deflector nozzle is used in the gas combustion tubes and in the radiant heating tubes. These tubes pass through both walls of the heat treatment furnace or the combustion tube of the enclosed heating tube. The combustion gas flow is swirled and brought to the tube centre. The deflecting nozzle is in the form of a cylindrical sleeve (4) with flange connection (5) and it is readily moved along the combustion tube (1). The latter has two concentric rings (2) forming a chamber (3) in which is held the flange of the deflecting nozzle.</p> |
