Objective
• Create a compact, portable steam power plant trainer that will
aid in the understanding of the Rankine cycle and automated
system control
Goals
•
•
Achieve fully automated system control
Rolling frame for ease of transport
▫ Dimensions of 4x2x3.5 feet
• Deliver the product complete with multiple lab experiments
• Produce an aesthetically pleasing product
4
Purpose
• Many students find difficulty understanding thermodynamics
without being able to apply theory to real world application
• Steam power plants account for roughly 78% of the world’s
electricity
• Students will learn the automated control system and will obtain
a working knowledge of how to check transducer readings

Lessons Learned
• Make efficient use of your time.
• Trust but verify.
• If it sounds too good to be true it
probably is.
• Doesn’t hurt to ask any company
for donations.
