Abstract
Heating element assemblies, heating furnaces incorporating heating element assemblies, methods to form heating element assemblies, methods to form heating furnaces and methods to reduce a magnetic field in a bifilar coil are disclosed. The heating element assembly includes two components, each component formed from heating element wire. The two components are spatially positioned and electrically arranged, relative to each other, so that an electrical current applied to the heating element assembly simultaneously travels through the two components in opposite directions.
Claims15
A method of forming a heating furnace, the method comprising:
- forming a heating element assembly by constructing a bifilar helical coil by intertwining two helical components, each helical component formed from heating element wire;
- and
- attaching the bifilar helical coil to an electrical circuit of a heating furnace,
- wherein the two helical components are spatially positioned and electrically arranged, relative to each other so that electrical current applied to the bifilar helical coil simultaneously travels through the two helical components in opposite directions.
A heating furnace, comprising:
- a heating element assembly, comprising two components, each component formed from heating element wire,
- wherein the two components are spatially dispersed over the same axis and positioned relative to each other so that an electrical current applied to the heating element is independently controlled in each of the two components.
