PROBLEM: IIC-21 BOOK: ENGINEERING THERMOFLUIDS, M. MASSOUD

The surface temperature of the hot side of the furnace wall is 1200 degrees C. It is desired to maintain the outside of the wall at 38 degrees C. A 152 mm of refractory silica is used adjacent to the combustion chamber and 10 mm of steel covers the outside. What thickness of insulating bricks is necessary between refractory and steel, if the heat loss should be kept at 788 W/m2? Use k=13.84 W/m-K for refractory silica; 0.15 for insulating brick, and 45 for steel.

The two materials most often used to produce semiconductor devices are ____________ and ____________.
