Abstract
An analysis of performance of the system utilizing waste heat energy from the plant is conducted. The working fluid is used Trifluoroethanol (TFEA). An analysis of performance of the system is performed in the thermal efficiency of Rankine cycle, the heat flow rate and the work for the inlet and outlet temperature difference of the waste heat gas. The thermal efficiency of Rankine cycle decreased monotonously with increases for the inlet and outlet temperature difference of the waste heat gas. As a result, the work becomes convex upward and has a maximum point. The thermal efficiency of Rankine cycle becomes about 14 to 24 % when the inlet temperature of the waste heat gas is 320℃.
