Device for modifying the temperature of a fibre-forming plate

A fibre forming device for fabricating mineral fibres, comprising a fibre forming spinner wheel pierced to enable fabrication of fibres by internal centrifuging, the fibre forming device comprising at least one annular burner producing an annular gas flow to stretch the fibres and an evacuation system for evacuating smoke created by said burner, wherein the fibre forming device further comprises a system adapted to vary the temperature of said fibre forming spinner wheel, the system adapted to vary the temperature of the fiber forming spinner wheel comprising an air circulation device adapted to control the smoke evacuation flow so as to control said temperature of the fiber forming spinner wheel, wherein the air circulation device includes a main pipe having a first end connected to a first secondary pipe used as an air outlet and a second end connected to a second secondary pipe in which the smoke of the smoke evacuation flow enters, said air circulation device further comprising a system configured to vary the smoke evacuation flow, the system configured to vary the smoke evacuation flow being configured to generate an additional flow, the system configured to vary the smoke evacuation flow being switchable between a first configuration in which the additional flow has a first direction that is the same direction as the smoke evacuation flow so that the additional flow is added to the smoke evacuation flow and a second configuration in which the additional flow has a second direction opposed to the first direction so that the additional flow opposes the smoke evacuation flow, so as to vary the smoke evacuation flow.
