• Description

• Ideal for students to gain insight into the first and second laws of thermodynamics
• Introduces students to industry-standard methods of analysing steam plant performance, including
Rankine Cycle Analysis and using the Willans Line
• Uses a simple two-cylinder steam motor and an electrically-heated boiler for easy understanding of
the main parts of a steam plant
• Self-contained in a mobile frame that includes all instruments needed for experiments
• Allows students to copy the Marcet Boiler Experiment to prove the pressure-temperature relationship
for saturated steam
• Connects to TecQuipment’s optional Versatile Data Acquisition System (VDAS®)

Specification
