Infrared and its Application in Industry
- Category: About Infrared Heat
Infrared radiation derives from two sources, natural and artificial. The most significant natural source is the sun: approximately 50% of the energy received by the earth from the sun is in the form of infrared energy. The absorption of radiant waves is highly selective which leads to the possibility of many different applications, a possibility not open to other forms of heating.
Commercially manufactured artificial sources (emitters) include incandescent, fluorescent, and high intensity lamps, flames, heaters, and artificial black body sources, i.e. many of the products sold by CCI Thermal.
In industry, infrared emitters are generally categorized into three wavelength bands, according to the intensity of the radiation and temperature at which the emitter operates:
- Short band: 0.75 to 2.0 microns; high intensity radiation, high temperature range 4000 - 2900°F (2200 - 1600°C)
- Medium, or intermediate band: 2.0 to 4.0 microns; medium intensity; temperature range 1800 - 1300°F (1000 - 700°C)
- Far, or long band: 4.0 to 10.0 microns; low intensity; temperature range 1300 - 572°F (700 - 300°C)
