Question:

An insulation system is to be selected for a furnace wall at 1000ºC using first a layer of mineral wool blocks followed by fiberglass boards. The outside of the insulation is exposed to an environment with h = 15 W/m2 ∙ ºC and T∞ = 40ºC. Using the data of Table 2-1, calculate the thickness of each insulating material such that the interface temperature is not greater than 400ºC and the outside temperature is not greater than 55ºC. Use mean values for the thermal conductivities. What is the heat loss in this wall in watts per square meter?
