Ncrements could be explained by raise around the energy generation from both Brayton and Rankine cycles. Exergy efficiencies of the cogeneration technique elevated from 14 to 26 as a consequence of exergy destruction reduction within the Brayton cycle.Exhaust gas mass flow rate (kg/s)1.J 2021,TIT, as shown in Figure 6a. Hence, the net energy production increment within the Rankine cycle is not surprising. Considering the fact that BODe and DO levels are kept D-Phenylalanine-d5 Epigenetics constant here, the total power requirement for the WWTP is calculated to be 204.eight kW. As might be seen from Figure 6b, a total energy of 219.five kW can be made from the cogeneration technique when the TIT is 1200 . Having said that, it needs to be noted that the self-sufficiency ratio varies from 76.6 631 to 107.2 when TIT alterations from 700 to 1200 . Consequently, it can be mentioned that TIT has the highest effect around the self-sufficiency with the proposed program.0.250 W net,Brayton W net,Rankine SSR 1.05 1 0.95 150 0.9 one hundred 0.85 0.eight 50 700 0.75 1200 W total,Cog 1.1.Mass flow rate (kg/s)Mass flow price (kg/s)1.0.0.Energy (kW)0.0.0.six mproduct 0.four 700 800 mwater 900 mair 10000.0.065Turbine inlet temperature (T16)Turbine inlet temperature (T16)(a)J 2021, four FOR PEER Assessment(b)Figure six.

Though energy and exergy effi30 ciencies of WWTP are 28.4 and 68.4 , the efficiencies for Rankine cycles are 43.3 and 53.two , respectively. Since the efficiency of your WWTP and Rankine cycle didn’t alter with TIT variation, they were not integrated to the graphs. Whereas energy efficiency on the 25 cogeneration technique increased from 14 to 27 , it elevated from 36 to 45 for the overall technique when TIT varied from 700 to 1200 . The purpose behind of those incre20 ments is usually explained by improve on the power generation from both Brayton and Rankine cycles. Exergy efficiencies of the 15 cogeneration program increased from 14 to 26 due Brayton Brayton Rankine Cog to exergy destruction reduction within the Brayton cycle.Energy EfficienciesExergy Efficiencies10OverallCogOverall10Turbine inlet temperature (T16)Turbine inlet temperature (T16)(a)(b)Figure 7.
