Hi professionals, im a student from philippines and im about to design a steam power plant with 74000 KW load. Our professor gave us a 3 steps at first chapter the first is that we assume the pressures needed from P2 to P8 where P2 = 8 MPa assume T2 at centigrade, and get the enthalpies up to P8 T2 must be greater than t5, and h5 = h4' + 150 h7' must not go beyond saturation line h8' must not go above saturation line look at my MS excel for more infos. second is we must get the percent extraction of <25% by getting h9 to h15 look at my MS excel for more infos. 3rd checking (look at my MS excel for more infos.) my problem now is the 3rd checking. im getting negative losses, low % output, im exceeding 30% at Qbd,Qref,Qfluegas.
