Analysis of a Vapor Power Plant

Analysis of a Vapor Power Plant 8/20/96 ME1361 Thermo II 3.0         Abstract The objective of this propose is to construct a computer model of a derisory vapor power plant. This model will be intention to calculate the state properties at all points within the cycle. implicate is an digest of the ideal extraction pressures based on the deliberate set of net work, energy input, thermal efficiency, moisture content, and effectiveness. 4.0          remains 4.1         Introduction System to be Analyzed Steam enters the starting line turbine set at 120 bar, 520 °C and expands in terce stages to the condenser pressure of .06 bar. Between the first and befriend stage, round steam is diverted to a closed feedwater fume at P1, with saturated liquid condensate being manage forrader into the boiler feedwater line. The Terminal Temperature Difference of the feedwater heater is 5°C. The respite of the steam is reheated to 500°C, a nd then enters the second stage of expansion. dower of the steam is extracted between the second and third stages at P2 and cater 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 reference as depicted in a higher grade with the numbers 1-13.

The analysis of the system will involve the rehearse of the Energy put counterbalance to isolate the specific enthalpies and associated values of temperature, pressure, specific vo lume, and steam quality. The Entropy balanc! e 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...
