Thanks IRstuff. I'm not sure this is my answer. When I use a refractory board for example, the data gives me certain thermal conductivity values for a certain temperature. If in the example above, which is K-Fac 19, I want to calculate for temperatures of 600°, 700°, 800° and 900°F what formula...
I use a multitude of refractories and insulation. The manufacturer of the materials has thermal conductivity information on the data sheets for certain temperatures. How do I calculate the thermal conductivity at temperatures other than what is on the sheet?
Example: HD Board: 0.570...
This question relates to calculating heat capacity in refractory and insulation boards used in furnaces and ovens. I have the thermal conductivity data (Btu/in/sq.ft/F) data points and the density of the materials. If the manufacturer does not show the heat capacity in Btu/lb DegreeF of the...
I have a standard 2800F high heat duty firebrick. Density average is 131 lbs/cu.ft.
How do I calculate the thermal conductivity (BTU-in/hr-sq. ft-f) at temperatures such as 500f, 1000f, 1500f and 2000f?
