3.0 Abstract
The objective of this study is to construct a computer model of a water vapor
power plant. This model will be used to calculate the state properties at all
points within the cycle. Included is an analysis of the ideal extraction
pressures based on the calculated values of net work, energy input, thermal
efficiency, moisture content, and effectiveness.
4.0 Body 4.1 Introduction System to be Analyzed Steam enters the
first turbine stage at 120 bar, 520 °C and expands in three stages to the
condenser pressure of .06 bar. Between the first and second stage, some steam is
diverted to a closed feedwater heater at P1, with saturated liquid condensate
being pumped ahead into the boiler feedwater line. The Terminal Temperature
Difference of the feedwater heater is 5°C. The rest of the steam is reheated to
500°C, and then enters the second stage of expansion. Part of the steam is
extracted between the second and......
