Abstract
The thermal efficiency of Low-grade Thermal Energy Conversion (LTEC) system is theoretically small. Therefore it is necessary to enhance on the thermal efficiency of the LTEC system. The Multi-Stage cycle was proposed aiming at optimizing the power output from low-temperature heat sources such as geothermal or waste heat. In this paper, it is shown on an influence of the heat source flow rate on the maximum power of Multi-Stage cycle that has independent equipment respectively. As a result, the maximum power output increases with an increase of the heat source flow rate. The maximum power output ratios of Multi-Stage cycle to Single-Stage cycle are almost same at any heat source flow rate conditions.
