Embodiment Construction

[0020] The following detailed description of the exemplary embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. Furthermore, the figures are not necessarily drawn to scale. Neither does the following detailed description limit the invention. Instead, the scope of the invention is defined by the appended claims. For simplicity, the following description refers to an Organic Rankine Cycle (ORC) used with a solar source for generating energy with an expander. However, the solar energy source could be different, or the expander could be replaced with another turbine for power generation. Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosed subject matter. Thus, appearances of the phrases "in one embodiment" or...

Abstract

A system for generating energy using an Organic Rankine Cycle (ORC) comprising a single closed loop configured to use an ORC fluid for the ORC, and a solar power source configured to use solar energy to transform an ORC liquid to a vaporized ORC.

Description

technical field [0001] Embodiments of the invention relate generally to power generation systems, and more specifically, to organic Rankine cycle (ORC) systems with solar energy sources. Background technique [0002] The Rankine cycle uses a working organic fluid in a closed loop to collect heat from a heat source or reservoir and to generate electricity by expanding a hot gaseous stream through a turbine or expander. This expanded stream is condensed in the condenser by transferring heat into the cold accumulator and pumped again to heating pressure to complete the cycle. It is known that solar energy sources are used as heat sources or heat stores. For example, concentrated solar power (CSP) systems use lenses or mirrors and tracking systems to concentrate sunlight from a large area into smaller beams. The accumulated heat is then used as a heat source for conventional power plants. A variety of aggregation techniques exist. Most of those that have been developed are p...
