Design Problem

Develop the preliminary design for a steam power plant. The plant must produce 1000 MW of electricity using water as the working fluid and a supercritical pressure of 24 MPa. The following is a list of requirements and constraints:

• maximum cycle temperature is 600?C and the maximum pressure is 24 MPa
• minimum quality at turbine exit is 90%
• turbine and turbine stages operate with isentropic efficiency of 85%
• pump operates with isentropic efficiency of 88%
• heat rejection at condenser using water from nearby lake

Include the following in your problem write-up/report:

a. Objective: statement of design objective

b. Background: a short paragraph related to chosen cycle and real world context, may also consider motivation for supercritical pressure, cite any references used.

c. Engineering model: indicate all key assumptions and system specifications

d. Description of system: schematic of cycle layout indicating all components and states; operating temperatures and pressures at key points within the system (show states and processes on T -s diagram)

e. Design process: description of rationale for all designer selected conditions, e.g., if reheat should be included and why, and at what pressure.

f. Analysis and calculations: complete analysis of system operating conditions, energy transfer rates, and performance

g. Results: include required energy (heat) input rate from source, mass flow rate, thermal efficiency of system

h. Conclusion: comment on results.
