Ask students to calculate the fuel costs to run one boiler in this plant at full capacity as specified on the flow diagram. Might also ask them to compare cost for using different fuels.

Familiarity with steam tables, First Law of Thermodynamics, efficiency

Learning Objectives:

(1) Apply the First Law of Thermodynamics to calculate the energy input required to a process (2) Calculate the cost to operate a process (3) (Optional) Search for information outside the current course text to complete engineering problems.

Technical Notes:

For an in-class exercise, instructor must provide information about heat transfer efficiency, fuel heating value, fuel costs. If given as homework, students can be required to research typical values for some or all of these parameters.

Text of Learning Exercise:

Take virtual tour of the Michigan State University Power Plant on the web. http://www.chems.msu.edu/classes/321/powerplant/

This website was originally developed by Dr. Carl Lira for one of his courses, so there may be a few comments in the text that are specific to his course.
