Abstract:
A method for sensing wear in a refractory lining in a vessel, comprising the steps of:installing a refractory support structure along the inside wall of a vessel having a height by securing said refractory support structure to the inside wall of the vessel to form a honeycomb-shaped structure defining a plurality of open cells; threading an elongated conductor through said honeycomb-shaped refractory support structure so that said conductor extends through a substantial portion of the height of said vessel; applying a refractory to said refractory support structure so as to fill said honeycomb-shaped structure with refractory and so as to embed said refractory support structure and said conductor inside said refractory; and connecting a means for sensing continuity across said conductor such that, as said refractory erodes due to an erosive action, said conductor is exposed to said erosive action, which is sensed by said means for sensing continuity.
