Infrared radiation
is a electromagnetic energy which is generated in a heat source. The
resultant energy can be controlled and directed to s specific objects where
it is absorbed and then heat is created. Infrared energy passes through air
at the speed of light with only negligible heating of airborne water vapour,
carbon dioxide and dust particles.
Infrared heating describes all emitted radiant energy between the
wavelengths of 0.67 and 1000 microns. For industrial heating applications
the practical wavelength range falls between 3 and 10 microns. Major forms
of electric infrared heating and metal -sheathed tubular elements, quartz
tubes & lamps, open coil wire elements and ceramic infrared emitters.
Ceramic emitters have the highest infrared efficiency of up to 96%. |
