A Low-grade Thermal Energy Conversion (LTEC) is paid attention in saving energy and generating power as environmental friendly energy. Over a long period of time, the thermal cycle efficiency has been used as mainly standard evaluation for energy system for generating power system, for example, a fossil fuel power plant, a nuclear power plant, a geothermal power plant, a wasted thermal energy conversion (WTEC) plant and an ocean thermal energy conversion (OTEC) plant, etc.. For the power plants using heat source below nearly 100℃ (WTEC, OTEC, and so on), a evaluation including pumping powers and net power etc. In this paper, the power plant using heat source below nearly 100℃ is called as LTEC. The thermodynamic analysis including pumping powers and net power is performed for LTEC. In this research, the ratio of net work to maximum work and some evaluation including using effectiveness-NTU are proposed on LTEC.
