Document Type and Number:
Japanese Patent JP4719271
Kind Code:
B2
Abstract:
An electrical heating element for vertical installation includes vertically suspended electrical resistance elements for the heating of furnaces in industrial operation, where each resistance element is formed of conductive legs, where along the length of the resistance elements are placed ceramic disks provided with holes, through which holes the relevant legs of the element pass. The ceramic disks are arranged between ceramic tubes and an upper metallic central rod is positioned within the ceramic tubes, which central rod supports the element and where the element is surrounded by a radiative tube. There are a number of upper ceramic tubes outside of the upper central rod with intermediate ceramic disks, and the central rod extends a certain distance down into the radiative tube.
