According to Harcros, Emisshield Inc's high emissivity
ceramic coating technology has expanded its applications into the petrochemical industry by increasing heat transfer in fired heaters, boilers and incinerators processes.
Referring to (1), M(T) is the thermal emissivity
of the observed object depending on its temperature (W/[m.
Each of these models can be classified into direct sky temperature models and atmospheric emissivity
And in most cases the camera readings need to be adjusted to take this emissivity
Thus, a selective coat is required to have a high absorption ([alpha]) in the solar wavelength range and an accompanying low thermal emissivity
([epsilon]) in the near infrared (NIR) and far-infrared (FIR) wavelength ranges.
22-23], they are never made from materials whose emissivity
is strongly directional.
One big source of error in temperature measurements of MCMs with an infrared camera is the emissivity
variation over their surface.
The painted asphaltic surface showed high thermal emissivity
and lost about half of its initial albedo (solar reflectance) within two years.
A common example is the use of a high emissivity
However few studies investigate the measurement of emissivity
of calibration load which is essential for industrial application.
Low-E or low emissivity
glasses act like transparent thermal insulations and they have much lower heat transfer comparing to normal glasses.
The coating line will be up and running from October 2012 and will produce high performance, low emissivity
glazing products to complement Pilkington's renowned K Glass, as well as its solar control glass products.
