An electric plate cooktop. A cooktop (American English), stovetop (Canadian and American English) or hob (British English), is a device commonly used for cooking that is commonly found in kitchens and used to apply heat to the base of pans or pots. Cooktops are often found integrated with an oven into a kitchen stove but may also be standalone ...
Electrical heating coils or halogen lamps are used as heating elements. Because of its physical characteristics, the cooktop heats more quickly, less afterheat remains, and only the plate heats up while the adjacent surface remains cool. These cooktops have a smooth surface and are thus easier to clean, but are markedly more expensive.
The procedures use a new hybrid test block made of aluminum and stainless steel. The proposed rule lists results of real lab tests conducted with the hybrid block. For comparable (large) cooking elements the following efficiencies were measured with ±0.5% repeatability: 70.7% - 73.6% for induction, 71.9% for electric coil, 43.9% for gas.
Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...
Induction heating is a non contact method of heating a conductive body by utilising a strong magnetic field.Supply (mains) frequency 50 Hz or 60 Hz induction heaters incorporate a coil directly fed from the electricity supply, typically for lower power industrial applications where lower surface temperatures are required.
An induction coil consists of two coils of insulated wire wound around a common iron core (M). [1] [7] One coil, called the primary winding (P), is made from relatively few (tens or hundreds) turns of coarse wire. [7] The other coil, the secondary winding, (S) typically consists of up to a million turns of fine wire (up to 40 gauge). [8] [1] [7]
