Thermodynamics
II Semester Design Project
Excel Program (http://crown.utpa.edu/thermo2/project/)
Due Date:
Thursday February 16th at 2:35pm
Description
: Design a
practical and efficient steam power plant.
You must work in groups of 3 to 4 students. The power plant may have several turbine
stages, open and closed feedwater heaters, reheat,
etc. The analysis will be based on the ideal Rankine
cycle where pump and turbine irreversibilities are
accounted for by the use of isentropic efficiencies (use 90% for all turbines
and pumps). Your analysis must use of a
computer program that calculates thermodynamic properties at each state in the
cycle. You must determine the efficiency of your power plant using the program
and demonstrate that you have optimized your design. You must turn in your program which allows
the user to easily change design parameters and recalculate efficiency and a
report that explains your design, the computer program, and the optimization
process that you followed. Your report
must also include an appendix with sample hand calculations for a sample power
plant used to verify the program output.
Grading:
10% of your final grade will be based on the design project.
1.
A
five page project report
(not including appendices of excel printout and hand
calculations) describing the design project and your final optimal design. The report must include a clear description
of the design process (how you arrived at your design and what variables were
considered). You must show a minimum of
three designs (not including the sample power plant below) with at least five
runs for each design that show optimization of design parameters. Your report must discuss the impact of cost
and feasibility on your design (maximum of 7 turbine stages, maximum temperature
of 600 oC,
and minimum pressure of 8.0 kPa).
2.
An
Excel program showing the results of the sample power plant design given below
and your optimum power plant design. You
grade will be based on the accuracy of the program (correctly using the WATER function)
and the presentation of the calculations (how easy it is to follow the
calculations).
3.
Hand calculations for the sample power plant
design shown below with comparisons made to the results from the Excel
program. The calculations must show
verification of calculated properties, work and heat transfer for individual
components, and overall efficiency.
