Furnace walls are lined by 3 layers: firebrick with a thickness of 6 in (k=0.95 Btu/h.ft. F), insulating brick (k-0.4 Btu/h.ft.°F) and common brick (k=0.8 Btu /h.ft.°F) Firebrick inlet temperature, T₁ = 1800°F, maximum insulating brick temperature, T₂ = 1720°F and T3 = 280°F. 1. Calculate the thickness of the insulating brick layer. 2. If the common brick is 9 in, calculate the exit temperature.
