<p>The invention relates to a sparger for the injection of an oxygen supply fraction into a fluidized bed reactor. The sparger comprises a distribution conduit for conducting the oxygen supply fraction, at least one lateral conduit and at least one nozzle provided with an orifice. The distribution conduit, the lateral conduit and the nozzle have at least partially thermally insulated external surfaces in order to inhibit the thermal transfer. The nozzle also includes a covering whose cross-section is larger than the cross-section of the orifice, the insulation substantially surrounding the covering along the entire length thereof, as well as a jacket of the covering which surrounds the same, the insulation being discontinued between the covering and the jacket thereof</p> |
