SUMMARY:Thermodynamic and Experimental Demonstration of Inverted Brayton Cy
 cle in Heat Recovery Applications
DESCRIPTION:Lecturer:Idan Chazan\n Faculty:Grand Technion Energy Program\n 
 Institute:Technion – Israel Institute of Technology\n Location:Classroom
  165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstract: \n Det
 ails: \n A deregulated electricity supply market\, based on the implementa
 tion of renewable energy power plants\, vastly promotes the emerging “di
 stributed power generation” concept. Therefore\, numerous small and effi
 cient power units are progressively introduced to the market in order to s
 atisfy the new demands and replace large outdated power plants. Hence\, si
 gnificant potential lies in the further improvement of small-scale power p
 roduction technologies such as micro gas turbines\, especially in cogenera
 tion systems.\nThe presented work deals with increasing the efficiency of 
 energy generation in decentralized energy supply through utilizing waste h
 eat. Waste heat typically contains one third of the total combustion energ
 y and is largely unused in contemporary small-scale power units. The curre
 nt effort investigates a new concept for the simultaneous production of ho
 t water and electrical energy\, based on the inverted Brayton cycle - expa
 nsion of hot exhaust gas at atmospheric pressure to sub-atmospheric condit
 ions\, extraction of heat in a recuperator and re-compression of the coole
 d gas back to atmospheric pressure. This heat recovery cycle generates pow
 er via expansion of the isobaric lines and can be used to drive an electri
 c generator\, while the heated coolant can be further used directly for co
 mbined heat and power generation.\nThe presentation will address the desig
 n and construction of a functional prototype where the inverted Brayton cy
 cle is experimentally demonstrated.
