EGNE 2303 Fall 2021 Term Project
EGNE 2303 Fall 2021 Time period Challenge Due: Thursday, Dec ninth @ midnight within the task dropbox Energy Cycle Evaluation with Regenerative Feedwater Heating You've been given (1) the specification sheet for a vapour energy plant with a steam turbine, and (2) the warmth stream diagram for the ability plant, together with regenerative feedwater heating system. Analyze this technique utilizing the thermo-fluids ideas developed on this course to find out the next: 1. Present a simplified schematic diagram of the ability plant, together with labels for every time period you utilize in your evaluation (i.e., ?turbine, hFW1, ?out) 2. ?out (in Btu/s) for every of the 5 turbine phases illustrated on the diagram three. Qin (in Btu/s) for every of the 4 phases of regenerative feedwater heating (i.e., how a lot enthalpy is added to the feedwater at every of the heating phases?) four. ?in (in Btu/s) to the boiler feed pumps 5. Thermal effectivity of the ability plant as illustrated (with regenerative feedwater heating) 6. ?out (in Btu/s) for all the turbine if there have been no regenerative feedwater heating system (i.e., if no steam was faraway from the turbine) 7. Thermal effectivity of the ability plant if there have been no regenerative feedwater heating system eight. Sketch the cycle with regenerative heating on a T-s diagram with every course of clearly labeled (ie, “turbine”, “RG1”, “RG2”, “pump”, and many others.). Embody a vapor dome. ? Present clear labels and mass balances for every mass stream calculated ? For every gadget (turbine, pump, boiler) analyzed, state mannequin assumptions and supply an vitality steadiness ? Make your options clear and simple to observe (I will likely be placing in minimal effort to interpret messy or disorganized work) Notes: • Use system knowledge given for regular operation at a turbine energy output of 16 MW (i.e. 16,000 kW) • “Warmth content material” values within the warmth stream diagram characterize particular enthalpy (h) • “Warmth consumption” values in spec sheet characterize fee of warmth stream into the boiler per kW of energy produced (i.e., items are in BTU/(kw*hr)) • Feedwater (i.e., fluid flowing from the condenser to the boiler) might be assumed to be liquid in any respect phases • Turbine and pump operation might be assumed to be adiabatic and internally reversible • Modifications in kinetic and potential vitality might be ignored • To calculate pump work, assume water stress on the pump inlet is at atmospheric stress (1 atm), and stress on the pump outlet is identical as on the turbine inlet • “Again stress” means stress on the outlet of the turbine (i.e, inlet of the condenser, or “condensation stress”) • Assume a fluid high quality of x = zero.9 on the turbine outlet • Knowledge for “condensate” might be ignored (i.e, use knowledge for “steam to condensate”) on far proper aspect of warmth stream diagram -- EGNE 2303 Autumn 2021 Challenge The task dropbox closes at midnight on December ninth.Thermodynamic Modeling of Regenerative FeedwaterThere's a specification sheet and a warmth stream diagram for a vapour energy plant with a steam turbine.Analyze this technique utilizing thermo-fluids ideas to seek out:Embody in your examine a simplified schematic mannequin of the ability plant with labels for every time period (turbine, hFW1, out).2.?out (in Btu/s) for every of the 5 turbine phases proven(i.e., how a lot enthalpy is added to the feedwater at every of the 4 heating phases?)four.

Thermal effectivity of the plant with out regenerative feedwater heating eight. Draw the cycle with regenerative heating on a T-s diagram, labeling every step (ie,“RG1”, “RG2”, “pump”, and many others.) a vapor dome? Label and mass steadiness every computed mass stream? Present an vitality steadiness for every gadget (turbine, pump, boiler).? Present simple, easy options (I will likely be placing in minimal effort to interpret messy or disorganized work)Notes:• Use system knowledge for typical working at 16 MW turbine energy (i.e. 16,000 kW)• Enthalpy values are proven within the warmth stream diagram (h)For instance, BTU/(kw*hr) on a spec sheet represents warmth stream into the boiler per kW of energy produced.• All phases of feedwater (from condenser to boiler) are thought-about to be liquid.• Turbine and pump motion is adiabatic and reversible.Potential and kinetic vitality modifications are uncared for.• Assume the water stress on the pump inlet is 1 atm and the stress on the pump exit is identical because the turbine inlet.• “Again stress” is the stress on the turbine's exit (or “condensation stress”).• Assume x = zero.9 on the turbine outlet• Ignore the info for “condensate” on the far proper aspect of the warmth stream diagram.
