ABSTRACT:
In a high temperature furnace adapted for fuel particle coating applications, an electrode ring forms a portion of the furnace wall, heating elements within the furnace being urged into conductive engagement with an internal surface of the electrode ring by means of adjustable spring mechanisms arranged outside the furnace and interconnected with the heating elements by elongated bolts in order to permit adjustment of the spring load without interrupting operation of the furnace. The spring mechanism provides nearly constant contact pressure between the heating elements and the electrode ring surface under varying thermal and physical conditions and prevents overheating and failure of the electrode ring.
