Steam Power Plant Analysis and Design Assignment 

Assignment task:
Your team is required to prepare a thermodynamic evaluation and conceptual-level proposal for a low-cost reconfiguration of an existing steam power plant. The operator wishes to optimize the thermodynamics to increase the plant power output while maintaining the current fuel consumption.
The existing steam power plant consists of one high (HP), one intermediate (IP) and one low-pressure (LP) turbine, connected to a three-phase electrical generator. Superheated steam for the turbines is produced in a simple water-intube boiler and superheater. The steam generator has the capacity for a single reheat. Reheating of the steam is currently done between the high and intermediate-pressure turbines. A closed feedwater-heater (CFWH) and pump combination are utilised as a regenerator. An air condenser with a pump operating at maximum output returns the liquid water to a mixing chamber to complete the thermodynamic cycle.

The steam turbine specifications indicate a maximum turbine operating temperature and pressure of 560°C and 120 bar respectively. The condensing pressure is specified as a maximum of 0.9 bar. Up to four turbine steam-extraction points are permitted at various pressure levels up to 45 bar. The source of heat for the steam generator is an external furnace. It combusts natural gas at 15% excess air. The combustion products are exhausted directly to the atmosphere. The natural gas has a composition (by volume) of:
Methane,            CH4 80.9%
Ethane,              C2H6 8.8%
Propane,            C3H8 5.2%
n-Butane,           C4H10 2.3%
Carbon dioxide, CO2 0.9%
Nitrogen,            N2 1.9%

Faster than expected turbine blade deterioration has been observed in the low-pressure turbine, leading to excessive maintenance costs.
Ambient air temperatures range from 1°C to 25°C at the plant site with a year-round average of 12°C. A large aquifer ground water source is available on-site. Several spare CFWH heat exchangers and pumps (as used in the existing plant), are in storage and available for use. Additional piping, valves, throttles, mixing chambers, etc. are expected low-level costs. Any other items proposed, must be discussed with the client before submission of the proposal. A data set is available (in appendix A) for thermodynamic analysis of the current steam power plant.

Deliverables:
A report is required with a maximum length of six pages for the body of the document. This report must detail the results of the thermodynamic analysis of the existing plant, the proposed plant modifications and the expected  performance improvements. Each change proposed should be justified in the report by logical, fundamental thermodynamics-based arguments. The report must include process (T-s) and flow diagrams of the existing and proposed plants. The process diagrams should be superimposed on the same saturation dome to graphically illustrate the improvements in plant performance. It is expected that this plot will take up a whole page of the report. To substantiate the performance claims in your report, your submission should include two appendices; the first should contain the detailed hand-written thermodynamics calculations for the existing plant and the second should contain the hand-written calculations for the proposed plant. The body of the report should not contain any thermodynamics calculations. Please do not include any additional appendices.
