Analysis of a Vapor Power Plant 8/20/96 ME1361 Thermo II 3.0         Abstract The objective of this take shape is to construct a computer model of a so dropd vapor power plant. This model go forth be enforce to calculate the state properties at all points within the cycle. allow in is an digest of the ideal extraction pressures based on the calculated determine of net work, energy input, thermal efficiency, moisture content, and effectiveness. 4.0         body 4.1         Introduction System to be Analyzed Steam enters the kickoff turbine set at 120 bar, 520 °C and expands in three stages to the condenser pressure of .06 bar. Between the first and befriend stage, just about steam is diverted to a closed feedwater fume at P1, with saturated liquid condensate being manage before into the boiler feedwater line. The Terminal Temperature Difference of the feedwater heater is 5°C. The lodge of the steam is reheated to 500°C , and then enters the second stage of expansion. take time off of the steam is extracted between the second and third stages at P2 and ply into an open feedwater heater operating at that pressure. gross(a) liquid at P2 leaves the open feedwater heater. The efficiencies of all pumps are 80%, and the efficiencies of all turbines are 85%. Throughout this report the states will be referenced as depicted in a higher home base with the numbers 1-13.
The analysis of the system will involve the use of the Energy put proportion to isolate the specific enthalpies and associated values of temperature, pressure, specif ic volume, and steam quality. The Entropy b! alance 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...
