A 0,244 m thick furnace wall is made of material with a thermal conductivity of 1.30 W / m.K. In order for the heat loss from the furnace to be 1130 W / m2, the wall will be insulated from the outside with a material with an average thermal conductivity of k: 0,346 W / m.K. Internal surface temperature is 1588 K and external surface temperature is 219 K. Calculate the required insulation thickness
