摘要：

Performance of organic Rankine cycle (ORC) system to recover low -temperature waste heat from aluminum reduction cell was analyzed. The temperature of waste heat is 80 degrees C similar to 200 degrees C and the flow rate is 3x10(5)m(3)/h. The pinch temperature difference between waste heat and working fluids is 10 degrees C. The results show that there is optimal evaporating temperature for maximum net power under the same pinch point. For heat source temperature range of 80 degrees C -140 degrees C and 150-170 degrees C, the working fluid given biggest net power is R227ea and R236fa, respectively. When the temperature is higher than 180 degrees C, R236ea generates the biggest net power. The variation of heat source temperature has important effect on net power. When the temperature decreases 10%, the net power will deviate 30% from the maximum value.
