Salamander Ceramic Infrared Emitters Technical Manual Page 10

Surface Temperature and Radiation Emissions:

        The curve shown below can be used as a quick reference to estimate the amount of infrared radiant energy emitted from a given source. The curves were derived using the Stefan-Boltzmann Law. For example, a 1000 °F (538 °C or 811 K) infrared source with an emissivity value of .80 (80%) will have an approximate radiant emission (from the curves below) of 12.5 Watt / in2. Using the Stefan-Boltzmann equation yields the following:

R = ( .80 )( 36.58072 x 10 -12 )[ (811)4] = 12.65 Watts / in2
