ABSTRACT:
An apparatus and a method for electrically heating a refractory lined process vessel or reactor by directly passing current through an electrically conductive refractory lining using electrical heating assemblies incorporating a resilient, convoluted nickel conductor. When the heating assemblies are attached to the electrically conductive refractory lining, an impressed voltage causes current to flow between the heating assemblies causing the refractory lining to be heated resistively.
