This paper studies the desired heat exchanger between the gas topping cycle and air bottoming cycle in terms of characteristics, performance, and optimizing design aspects of the plant power generation cycle. The performance of the combined power cycle with the heat exchanger is investigated under different operating conditions for different available types and arrangements of such heat exchangers. Various mathematical models including geometry, operation, performance, and economy are introduced. Several numerical correlations are worked on to transform the literature published data to thermoeconomic mathematical relationships. A computer software package is established to carry out the evaluation, design, and optimization processes. The Plain plate-fin surface 2.0 heat exchangers are employed with unmixed fluids for cross-flow and counter-flow arrangements, while two Westinghouse gas turbines of 160 and 32.2 MW, are implemented, transporting 435 kg/s flue gases and 199 kg/s air, respectively. The study considers simple cycles, cycles with one intercooler, or with two intercoolers. Various and detailed parametric, and optimization study outcomes are achieved. There is a linear relation between counter-flow heat exchanger effectiveness and plant power cycle efficiency, with a rate of each 0.1 effectiveness improvement gives 1.25 % rise in the efficiency. For Plain Plate-Fin Surface 2.00, counter-flow arrangement, at the optimum line, the net savings grow up to 30 and 54%, for plants with one and two intercoolers, respectively, based on the simple case with 2.7 MUSD. This heat exchanger augmented with two intercoolers in the cycle, through dimensions of 1.77 m x 5.03 m x 10.06 m, is the optimum one, has the highest energy savings, efficiency, and effectiveness, with net energy savings of 4.1 MUSD and mass of 136 Ton.
It’s very good to mention very important general guide points, that help the candidate goes straight away in the research work. These include a list of valuable points.
The candidate student should well know a set of basic items; these include the following; 1. Defining the desired research point. 2. Studying and understanding the material related to the point. 3. Determining the main study objectives. 4. Selecting the method and specifying the methodology. 5. Practicing the method facilities concerning analytical, numerical, experimental and/or software packages. It's very good to mention very important general guide points, that help the candidate goes straight away in the research work. These could include the following points; 1. Read as most as you can; notes, articles, papers, thesis, and chapters in books that are related to your point. 2. Document any hint that comes to your mind before you miss it. Try to live with your research point, don't exhaust yourself. Organize your time. 3. Try not to miss seminars, discussions, meetings, presentations, and trips. Talk to people and get advices and recommendations. 4. Make use of WORD (or other) to well document your material using the automated features. 5. Make use of MENDELEY (or other) to automatically handle the references in the text and as an automatic list at the end of the text. 6. Literature survey, where the student is required to cover the recent published titles. This usually comes in a chapter which summarizes other's research work. 7. Make use of GRAMARLY (or other) to fix your text wording. 8. Make a proposal for the expected contents of your thesis. Open a file for each chapter, where you start to write things that are related. 9. Make use of EXCELL (or other) to calculate and present your results. 6. Make use of "What; When; Where; Why; and How", to achieve a very good discussion for your results. Try to justify any up normal trends. 7. Make use of your colleagues and specialists reading for you. Try to upgrade your language. 8. Once you have enough material, go straight for publishing. 9. Try to give an attention to three items; the title, abstract, and conclusions. 10. Make sure you keep a very good relation with your supervisor and other institute staff members. Be helpful to other researchers. 11. Be Patient and optimistic person. Don't forget to ask Allah your needs. We all in needs to Allah. Good luck. 12. At the end, CONGTRATULATION!!!
