SUMMARY

This discussion focuses on designing a power generating system utilizing a hot air stream at 700°C and 8 Bar, a hot steam stream at 350°C and 1 Bar, and a lake with a static temperature of 16°C. The proposed approach is to implement a Rankine cycle system, leveraging the available steam source. The user seeks guidance on incorporating the lake water and hot air stream into the design and calculating the enthalpy changes for the steam before and after turbine entry to determine power output.

PREREQUISITES
  • Understanding of Rankine cycle thermodynamics
  • Knowledge of steam turbine operation and efficiency
  • Familiarity with enthalpy calculations in thermodynamic systems
  • Basic principles of heat transfer and fluid dynamics
NEXT STEPS
  • Research Rankine cycle efficiency optimization techniques
  • Learn about steam turbine performance metrics and calculations
  • Study methods for integrating multiple heat sources in power generation
  • Explore enthalpy calculation methods for steam and water in thermodynamic cycles
USEFUL FOR

Engineers, energy system designers, and students in thermodynamics or mechanical engineering looking to enhance their understanding of power generation systems and thermodynamic cycles.

Thread moved to the schoolwork forums and OP has been reminded to always show their work on schoolwork problems.
TL;DR Summary: I've been asked to design a power generating system. I could really use some help on how to approach this question, as I cant really find something like that in my study meterial.

So I've been asked to design a system that would produce the biggest amount of power possible, using these parameters:

A Hot air stream, with a temperature of 700C, preasure of 8 Bar and a flow rate of 10 KG/min.
A stream of hot steam, with a temperature of 350C, preasure of 1 BAR, and a flow rate of 10KG/min.
A lake with a static temperature of 16C, and the air around the system which is at 22C and 1 Bar.

Any suggestions on how to approach this?

I was thinking of making a Rankine cycle system, since i'm supplied with a source of steam. The thing is, i'm not sure how to incorporate the water of the lake or the hot air stream into it. Also, while finding the Enthalpy for the steam before entering a turbine is easy enough, i'm not sure how to find the Enthalpy once it exits to calculate to amount of power the turbine generates.

Does your textbook / do your lecture notes have anything about steam turbines ?
