Radial Blade Heating Device
US Patent:
4179603, Dec 18, 1979
Filed:

Appl. No.:
5/853274
Inventors:

International Classification:
H05B 302
US Classification:
219538
Abstract:
An electric radial blade type heating element is provided for industrial furnaces or other heated devices in which the electrical conductors are relatively thin flat strips or blades, rectangular in cross section and free floating relative to the insulating support structure of the element. The conductors are arrayed in a radially diverging relationship to maximize the exposure of the radiating surfaces which minimizes the pocketing of released heat and overheating of the elements. Means are provided to pass a fluid over the conductors when the element is mounted within a radiant tube to reduce oxidation of the element and the interior surface of the radiant tube. The heating element support structure is not dependent on the conductors for strength or rigidity, thereby rendering the element equally suitable for vertical as well as horizontal installation. The element may be used to directly heat a furnace, or may be mounted in a radiant tube to heat the radiant tube. The number of radially arranged conductors in the array, their thicknesses and widths are functions of the heat release desired and, if used in a radiant tube, the diameter of the enclosing tube.
