What is heating element ? Which wire is used as heating element in electric heater?
1 Answer
The wire which is used to convert electrical heater into heat energy in any heating devices is called heating element. Nichrome wire is used as heating element in electric heater.
Nichrome: Most resistance wire heating elements use nichrome 80/20 (80% Nickel, 20% Chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time.
Touch a probe on the multitester to each screw on the element. If you get no reading, or a maximum reading, the element is bad. Elements do have some resistance, so a reading of 10-16 ohms is normal, with higher ohm readings for 3,500 watt elements and lower readings for 5,500 watt elements.
An industrial heating element provides heat in a variety of capacities for manufactures and producers of every imaginable product. With such a wide variety of heating element options, it can be a challenge to find the prefect element for your task. The first step toward choosing the most efficient and effective heating element for any process starts with the identification of some of the main types of heating elements available for industrial use.
Immersion elements: Immersion heaters quickly heat liquids for different industrial uses.
Tubular heaters: Tubular heating elements are some of the most common forms of industrial heating elements.
Flanged heaters: Flanged heating elements apply direct heat to liquids and can contain both hairpin and tubular heating elements contained in a small sheath.
Cartridge heaters: Cartridge heating elements look like florescent light bulbs.
Knowing the variety of heating options available can help any manufacturer choose the best heating elements for their processes.
