Design and analyze a base steam power-plant operating at
Boiler pressure 900 psia
Boiler temperature 800F
And Condenser pressure 2 psia
With 9, - 0.827 and Op - 0.80
Optimize the system for highest efficiency by varying the number of feed-water heaters (use
spreadsheet), and show the results in tabular form and plot the number of FWH vs. thermal efficiency of
the steam power-plant.
For No. 6 fuel oil with a heating value of 140,000 Btu/gal ($2.00/gal) and a boiler efficiency Ils of 90%,
calculate the cost ($/kwh) of electricity produced.
