WebThe heat rejection from S2 to S3 occurs at the cooler saturation temperature of 45.8 C. As a quick check, we can find the Rankine cycle's thermal efficiency by applying the relation for Carnot efficiency to the mean Rankine cycle temperatures: h = ( Ta - Tr ) / Ta = (226.7 - 45.8) / (226.7+273.15) = 36.2%. WebQuestion #195279. A turbine with one extraction for regenerative feed water heating receives steam with. an enthalpy of 3373 kJ/kg and discharges it with an exhaust enthalpy of 2326 kJ/kg. The ideal regenerative feed water heater receives 11,338 kg/h of extracted steam at. 345kPa (whose h=2745kJ/kg). The feedwater (condensate from the condenser)

WebNov 23, 2014 · Answers and Replies. i know that regeneration is heating the feed water by the bled steam from the turbine to reduce the sensible heat addition by the boiler but doesn't that also causes a reduction in the steam turbine work because we've taken some steam from it . Yes, there is a minor reduction in the amount of work extracted from the turbine. WebHowever, each subsequent stage of regenerative heating contributes less and less to the rise in thermal efficiency, as can be seen from the graph in Fig. 11.30, where the rate of increase in the thermal efficiency of a regenerative cycle, , is plotted as a function of the number of regenerative heating stages, n; the graph is plotted for the case of uniform …
