Low-grade Thermal Energy Conversion (LTEC) utilizes the unutilized heat source. The important to improvement performance of LTEC system is the thermal efficiency enhancement because of a small temperature difference between high- and low-temperature heat sources. This paper investigates on the influence of the temperature difference between high- and low-temperature heat sources on the system performance of the multi-stage Rankine cycle. As a result, maximum power and heat sources temperature change increase with an increase of the temperature difference. On the other hand, the temperature difference has little influence on the effectiveness ratio of maximum power output.
