A furnace wall consists of 25 cm firebrick, 30 cm insulating brick and 25 cm building brick , respectively. The inside wall is a temperature of 800C and the atmospheric temperature is 15 degrees * C C. Calculate the heat loss per of wall area and the temperatures of the interfaces of the furnace. The heat transfer coefficient for the outside surface is 10 W/m^ ^ 2.k and the thermal conductivities of the firebrick , insulating brick, and building brick are 6, 0.3 and 0.8W / m respectively. m^ ^ 2; tc=^ * 1 point t 1 =800^ C; t a iota c; t 2 =15^ o; 86.363 degrees * C 73.148°C 74.059 degrees * C; 68.983 degrees * C
