Experimental and Numerical Study of a Microcogeneration Stirling Unit under On–Off Cycling Operation
Publikováno v:
Energies, Vol 14, Iss 4, p 801 (2021)
Stirling units are a viable option for micro-cogeneration applications, but they operate often with multiple daily startups and shutdowns due to the variability of load profiles. This work focused on the experimental and numerical study of a small-si

The present work aims to investigate the potential advantages in using a novel wet and dry configuration for heat rejection units in ORC power plants. The reference case is a geothermal power plant that exploits a low temperature brine and uses a clo

La transizione ecologica è una delle sfide più difficili della nostra storia recente. Richiede tempo, equilibrio e la consapevolezza che non può seguire lo stesso percorso per tutti i Paesi. In più, conta numerosi nemici: oltre ai negazionisti de

SOLARPACES 2019: International Conference on Concentrating Solar Power and Chemical Energy Systems
In the near future, a significant increase of the fraction of electricity produced by variable renewable energy sources (wind and PV) is expected. In this scenario, concentrating solar power (CSP) plants, thanks to the implementation of cost-competit

The application of CO2 power cycles has proved to be particularly advantageous to exploit high-temperature heat sources (500–800 °C) in the case of available low-temperature heat sinks (15–25 °C). Otherwise, the efficiency of these cycles is st

The calculation of the performance of an ORC (Organic Rankine Cycle) and its components (in particularly the turbine) is generally not a trivial task because of the lack of a proper instrumentation, the inaccuracy of the available measurements and th

Low-medium temperature heat sources in the range 5–50 MWth are made available by many industrial fields but they may also be of interest for biomass, geothermal and solar energy applications. ORC has been proposed in the last 20 years as a reliable
