Description
The present study looks at the feasibility of a small scale power plant configuration with nominal electric output of 100 kWe fed from low potential thermal heat source, especially from flat thermal solar collectors operating in the range of 343to 373K. The power plant uses multiple cascaded sorption heat transformers (AbHT and AdHT) coupled with an Organic Rankine Cycle (ORC). The study revealed for the proposed system, that it would be possible to generate electrical power over the entire range of the proposed temperature within the considered hypotheses. The work was split in two parts. The first part presents a complete state of the art of the thermal cascade assembly of the upgrade of low-potential heat energy technology and small-power generation system. Moreover, the power plant configuration with cascaded sorption heat transformers and small-power generation device is described, followed by the presentation of the developed mathematical model with all equations and fundamental laws specific to each compartment of the proposed power plant. The main results, discussions and conclusions are presented separately in a second part of this work.
