Abstract
A mineral fiber forming device including: a centrifuge configured to rotate about a rotation axis, the centrifuge including an annular wall pierced by a plurality of orifices, the axis of symmetry of the annular wall being the rotation axis; a first annular inductor configured to heat a top part of the annular wall; a second annular inductor configured to heat a bottom part of the annular wall. The device makes it possible to increase its energy efficiency and very greatly reduce, even cancel altogether, its carbon dioxide emission level.

A mineral fiber forming device for producing an insulating product comprising:
- a centrifuge configurated to rotate about a rotation axis, the centrifuge comprising an annular wall pierced by a plurality of orifices, an axis of symmetry of the annular wall being the rotation axis, and the annular wall having a height,
- a first annular inductor positioned above a top part of the annular wall and configured to heat the top part of the annular wall,
- a second annular inductor positioned below a bottom part of the annular wall and configured to heat the bottom part of the annular wall,
- a conveyor configured to receive and convey mineral fibers,
- a first blowing ring configured to blow air on the mineral fibers that are about to leave through the plurality of orifices in the annular wall so as to drive them to the conveyor,
- wherein a temperature gradient is provided over the height of the annular wall of the centrifuge.
