Question

The surface of a furnace wall is at a temperature of 1200°C. The outside wall temperature is 38°C. The furnace wall construction has 15 Cm of refractory material,), k = 1.73 W/m-K., and the outside wall is 1-cm steel, k = 44 W/m-K. What thickness of refractory brick must be used between the refractory material and the wall if the heat loss is not to exceed 0.7 kW/m²? The thermal conductivity of the brick is 0.34 W/m-K.

6. The surface of a furnace wall is at a temperature of 1200°C. The outside
wall temperature is 38°C. The furnace wall construction has 15 Cm of
refractory material,), k = 1.73 W/m-K., and the outside wall is 1-cm steel, k
= 44 W/m-K. What thickness of refractory brick must be used between the
refractory material and the wall if the heat loss is not to exceed 0.7
kW/m?? The thermal conductivity of the brick is 0.34 W /m-K.
