An industrial furnace is made of fireclay brick of thickness L₁ = 0.25 m and thermal conductivity k₁ = 1.0 W/(m +°C). The outside surface is to be insulated with material of thermal conductivity k₂ = 0.05 W/(m. °C). Determine the thickness of the insulation layer in order to limit the heat loss from the furnace wall to q = 1000 W/m² when the inside surface of the wall is at 1030°C and the outside surface at 30°C.
