This study aims to achieve exergy distribution in a turbine system for a 1000 MW double reheat ultra-supercritical power plant. An exergy balance equation is used to identify the real points of energy loss in the turbine system, which can provide a reference for optimizing operation and conserving energy. Results show that irreversibilities yield the highest exergy loss in the turbine, particularly...
With the growing energy crisis and environmental pollution worldwide, the environmental benefits of biodiesel have made it a more attractive product. However, the production of biodiesel feedstock can only satisfy a small fraction of the demand for transportation fuels, and the cost of this feedstock is the main obstacle to the commercialization of biodiesel. The marine microalgae Schizochytrium is...
It is important to improve the heat utilization efficiency for the waste heat as well as the geothermal heat because both of them will exhaust to the environment or flow back to the ground directly after the energy was recovered. In order to achieve that, a novel cascading cycle driven by the low temperature heat source was developed. This cycle featured for the high exergy efficiency for the heat...
