6. A furnace wall consists of 250 mm fiber brick, 125 mm insulating brick, and 250 mm building brick. The inside wall is at a temperature of 600°C and the atmospheric temperature is 20°C. Calculate the heat loss per m of wall area and the temperature of the outside wall surface of the furnace and the temperature at each interface throughout the wall. The heat transfer coefficient for the outside surface is 10 W/m2 "k and the thermal conductivities of the fiber brick, insulating brick and the building brick are 1.4,0.2 and 0.7 W/m.°C respectively.
