Design a steam power plant that can achieve an actual overall thermal efficiency of at
least 46 percent under the conditions that all tu
ines have isentropic efficiencies of 90%, all
pumps have isentropic efficiencies of 85%, all open feed-water heaters have effectiveness of
100%, and all closed feed-water heaters have effectiveness of 85%.
Start with a simple 4-component steam power plant and then consider modifying it by
adding additional components such as re-heaters, re-generators (open and closed feed-water
heaters), a combination of re-heater(s) and re-generator(s), as well as changing operating
conditions, etc. to achieve an actual overall cycle thermal efficiency of 46% or higher for
practical operating conditions.
Prepare an engineering report describing your design criteria, methodology, analysis,
and results. Justify your design criteria and any assumptions made. Your design report must
include, but is not limited to, the following parts:
a)​ A schematic diagram of each plant (design) with numbering and nomenclatures as
specified in your textbook.
)​ Design criteria based on consideration of the recommended practices (operating
conditions of pressure, temperature, steam quality, etc.; materials selection; cost,
safety and environmental factors).
c)​ Detailed calculations of each cycle investigated. Specify all input data for each cycle
at the beginning of your calculations.
d)​ A schematic T-s diagram with labeled thermodynamic states of the working fluid at
different states in the cycle for each case.
e)​ Operating conditions for each component of the plant and related thermodynamic
properties of the working fluid (water).
f)​ Comparison of actual and ideal cycle for the same operating conditions.
g)​ Tables summarizing calculations and results for various cases considered.
h)​ Discussion of various cycles attempted to meet the goal, as well as the positive and
negative aspects of your design.
i)​ A summary of your design project (the second page of your report, after the title
page).
j)​ Conclusions and recommendations.
o You need to use Steam Table to find all properties.
o No need for code, do calculations by hand and show details of calculations for EACH cycle
o However, you need to type the introduction, summary, discussion, and conclusions.
