@article{(Open Science Index):https://publications.waset.org/pdf/5314, title = {Recent Advances in Energy Materials for Hot Sections of Modern Gas-Turbine Engines}, author = {Zainul Huda}, country = {}, institution = {}, abstract = {This presentation reviews recent advances in superalloys and thermal barrier coating (TBC) for application in hot sections of energy-efficient gas-turbine engines. It has been reviewed that in the modern combined-cycle gas turbines (CCGT) applying single-crystal energy materials (SC superalloys) and thermal barrier coatings (TBC), and – in one design – closed-loop steam cooling, thermal efficiency can reach more than 60%. These technological advancements contribute to profitable and clean power generation with reduced emission. Alternatively, the use of advanced superalloys (e.g. GTD-111 superalloy, Allvac 718Plus superalloy) and advanced thermal barrier coatings (TBC) in modern gas-turbines has been shown to yield higher energy-efficiency in power generation. }, journal = {International Journal of Materials and Metallurgical Engineering}, volume = {6}, number = {2}, year = {2012}, pages = {176 - 178}, ee = {https://publications.waset.org/pdf/5314}, url = {https://publications.waset.org/vol/62}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 62, 2012}, }
