Analysis of a Vapor Power Plant 8/20/96 ME1361 Thermo II 3.0         Abstract The objective of this furbish up is to construct a computer model of a firm vapor power plant. This model leave be drop to calculate the state properties at all points within the cycle. involve is an digest of the ideal extraction pressures based on the measured determine of net work, energy input, thermal efficiency, moisture content, and effectiveness. 4.0         embody 4.1         Introduction System to be Analyzed Steam enters the rootage turbine set at 120 bar, 520 °C and expands in one-third stages to the condenser pressure of .06 bar. Between the first and befriend stage, roughly steam is diverted to a closed feedwater fume at P1, with saturated liquid condensate being manage in the lead into the boiler feedwater line. The Terminal Temperature Difference of the feedwater heater is 5°C. The inhabit of the steam is reheated to 500°C, a nd then enters the second stage of expansion. expound of the steam is extracted between the second and third stages at P2 and feed into an open feedwater heater operating at that pressure. gross(a) liquid at P2 leaves the open feedwater heater. The efficiencies of all pumps be 80%, and the efficiencies of all turbines are 85%. Throughout this report the states will be write as depicted in a higher maneuver with the numbers 1-13.
The analysis of the system will involve the subroutine of the Energy put balance wheel to isolate the specific enthalpies and associated values of temperature, pressure, specific v olume, and steam quality. The Entropy balan! ce equation will be use to calculate the specific entropy at all the above noted states. Energy Rate Balance (assume KE&PE=0) dEcv/dt = Qcv-Wcv+Smi(hi) - Sme(he) Entropy Rate Balance dScv/dt = SQj/Tj + Smi(si) - Sme(se) + scv For simplicity, it is fake in all calculations that...
