In the figure below, a cross-section of a large electric-arc furnace wall is depicted. The exterior of the brick wall (L1=29-cm, k1=2-W/m.K) is covered with an insulation material (L2=13-cm). Heat flux input at the interior surface of the furnace results in T=1,094°C, T;=681°C, and =205°C. Assuming one dimensional steady conduction, negligible contact resistance, and uniform properties, estimate the thermal conductivity of the insulation material (in W/m.K). T; T5,0 brick wall insulation

heat transfer

In the figure below, a cross-section of a large electric-arc furnace wall is depicted. The exterior of the brick wall (L1=29-cm, kj=2-W/m.K) is covered with an insulation material (L2=13-cm). Heat flux input at the interior surface of the furnace results in Ts=1,094°C, T;=681°C, and =205°C. Assuming one dimensional steady conduction, negligible contact resistance, and uniform properties, estimate the thermal conductivity of the insulation material (in W/m.K). T5,0 brick wall insulation
