미활용열 이용 온도차발전 및 담수화 성능향상 방안

Abstract

Research is being carried out on ways to improve the efficiency of temperature differential power generation using seawater and various unused heat in land and sea. Cycle modeling and analysis, component performance analysis and design, and device performance assessment are under way for new and new materials that can improve efficiency and power in existing temperature difference power generation at 70°C temperature difference by utilizing geothermal heat of 75°C or higher, industrial process heat, and ship waste heat as a source of evaporator heat. In this paper, we would like to introduce the analysis of the high-efficiency temperature difference power cycle applied by ejector-pump according to various variables such as working fluid, heat source and thermal sleep temperature, pressure recovery rate of ejector and flow distribution rate. In addition, with regard to the evaluation of the power performance of the temperature difference power generation using modular thermocouples, we would like to introduce the design of ORC modular, the analysis of heat exchange model for improving the power.
