Recovery of the low-temperature waste heat for electricity generation has been gaining a significant interest. An Inverted Brayton Cycle (IBC) is often employed to convert waste-heat while thermal efficiency and specific work output are poor. In this paper, new energy recovery scheme introduced incorporating IBC with Regenerative Heat Mass Exchanger (RHME). The RHME mass exchanger that consolid...

Basing on results of previous studies, the efficiency of a Brayton/Hirn combined cycle, fuelled with a clean syngas produced by means of biomass gasification and equipped with CO2 removal by chemical absorption, resulted 33.94%, considering also the separated CO2 compression process. The specific CO2 emission of the power plant was 178 kg/MWh. In comparison with values previously found for an I...

This note corrects a discrepancy between the semantics and the algorithm of the multiple until operator of CSL, like in Pr>0.0025(a U[1,2] b U[3,4] c), of the article: Model-checking continuous-time Markov chains by Aziz, Sanwal, Singhal and Brayton, TOCL 1(1), July 2000, pp. 162–170.

Considering a simple regenerative Brayton cycle, the impact of using different fuel blends containing variable volumetric percentage hydrogen in methane was analysed. Due to potential combustion gas turbines reduce overall CO2 emissions and dependency on natural gas, further research is needed understand thermodynamic cycle. For that purpose, qualitative analysis carried out assess exergetic en...

Many industrial processes use hot air as a medium. This is especially relevant for drying. Nowadays, most of them consume fossil energy. study analyses an innovative facility direct solar heating up to 400 °C. For this aim, medium-scale field linear Fresnel collectors proposed heat ambient inside it. No other dedicated transfer fluid necessary. A simpler layout avoids costs, hurdles, and risks ...

The use of the organic Rankine cycle (ORC), flash (OFC) and Kalina (KC) is proposed to enhance electricity generated by a supercritical CO2 recompression Brayton (SCRB) cycle. Novel comparisons SCRB/ORC, SCRB/OFC SCRB/KC integrated plants from thermodynamic, exergoeconomic sustainability perspectives are performed choose most appropriate bottoming for waste heat recovery SCRB For comprehensiven...

Black holes are arguably the most extreme regions of universe. Yet, they also utterly inaccessible to experimentation, and even just indirect observation poses significant technical challenges. The phenomenological approach thermodynamics is uniquely suited explore at least some physical properties such scenarios, this has motivated study so-called holographic engines. We show that efficiency a...
