This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rainbow field test sponsored by the Electric Power Research Institute (EPRI) under contract RP2465-1 was performed to evaluate the comparative hot corrosion resistance of commercially available coatings for gas turbine blades and vanes. The 10,307-hr field test was carried out on a Solar Turbines Incorporated Centaur T-4000 gas turbine operating on a lower grade liquid fuel at the Favianca site of the Owens-Illinois, Inc. glass manufacturing facility in Valera, Venezuela. This paper reviews the results of an evaluation of the performance of three modified aluminides, three MCrAlY overlays, and one duplex NiCoCrAlY/ZrO2-2OY2O3 overlay applied as coatings to the first-stage MAR-M421 and IN-738LC rotor blades, Visual and metallographic examination and remnant coating thickness measurements established that the MCrAlY overlay coatings were generally more effective than a Cr-aluminide and two Pt-aluminides protecting the first-stage blades. Individual differences between the various coatings were established. A remnant coating thickness index (RCTI) was defined to express coating survival and protectiveness quantitatively. The results of blade airfoil temperature estimates were correlated with the hot corrosion morphology.

Book excerpt: A rainbow field test sponsored by the Electric Power Research Institute (EPRI) under contract RP 2465-1 was performed to evaluate the comparative hot corrosion resistance of commercially available coatings for gas turbine blades and vanes. A 10,307-hr field test was carried out on a Solar Centaur T-4000 gas turbine operating on a lower grade liquid fuel at the Owens-Illinois, Inc. glass manufacturing facility in Valera, Venezuela. This paper reviews the results of an evaluation of the performance of a simple aluminide, a Pt, Rh-aluminide and two MCrAlY (M = Co, NiCo) overlays applied to the first stage FSX-414 vanes. As found for blade coatings, on the basis of visual and metallographic examination, and remnant coating thickness measurements, it was established that the MCrAlY coatings were generally more effective than the simple aluminide and the Pt, Rh-aluminide in providing protection to first stage vanes. A remnant coating thickness index (RCTT) was used to express coating survival and protectiveness quantitatively. The results of the study have been compared with literature.

This book was released on 2018-08-13 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Mach 0.3 burner rig test program was conducted to examine the sensitivity of thermal barrier coatings to Na and V contaminated combustion gases simulating potential utility gas turbine environments. Coating life of the standard ZrO2-12Y2O3/Ni-16.2Cr-5.6Al-0.6Y NASA thermal barrier coating system which was developed for aircraft gas turbines was significantly reduced in such environments. Two thermal barrier coating systems, Ca2SiO4/Ni-16.2Cr-5.6Al-0.6Y and ZrO2-8Y2O3/Ni-16.4Cr-5.1Al-0.15Y and a less insulative cermet coating system, 50 volume percent MgO-50 volume percent Ni-19.6Cr-17.1Al-0.97Y/Ni-16.2Cr-5.6Al-0.6Y, were identified as having much improved corrosion resistance compared to the standard coating.

Available in PDF, EPUB and Kindle. Book excerpt: Worldwide, carbon dioxide emission reductions are in progress following the Kyoto Protocol implementation programme to mitigate climate change. More stringent reductions are expected to follow the present programme which ends in 2012. In addition to reducing carbon dioxide emissions, the major climate change mitigation policy is the elimination of waste. This project addresses both aspects, by facilitating the use of biomass and waste fuels in the gas turbines of highly efficient, integrated gasification combined cycle electricity generating units. Gases from the gasification of these fuels contain potentially damaging contaminants which, when combusted in gas turbines, will initiate hot corrosion. To resist hot corrosion, but still maximise gas turbine efficiency, the hot components of gas turbines require protective coatings. Five activities in this project required original research to meet the objectives. Firstly, to identify potentially damaging species in gasifier gases, which could remain after hot gas cleaning and, following combustion, initiate hot corrosion along the gas path of the gas turbine. Thermodynamic assessments, using MTDATA software, identified cadmium and lead species that could initiate hot corrosion in the gas turbine. The second research activity, involved Type II hot corrosion tests of the identified species on superalloys and typical commercial coatings. These tests simulated the same corrosion environment as in industrial high temperature gas turbine operation. Test results confirmed the thermodynamic assessments, with hot corrosion being initiated on all items tested, and was worse with lead and/or cadmium additions. The third research activity was to develop novel hot corrosion protective coatings. The approach was to develop the most economic coatings, which would provide comparable, or superior, hot corrosion performance to that provided by well proven commercial coatings already used with fossil fuel firing. From previous research at.

Available in PDF, EPUB and Kindle. Book excerpt: The Gas Turbine Engineering Handbook has been the standard for engineers involved in the design, selection, and operation of gas turbines. This revision includes new case histories, the latest techniques, and new designs to comply with recently passed legislation. By keeping the book up to date with new, emerging topics, Boyce ensures that this book will remain the standard and most widely used book in this field. The new Third Edition of the Gas Turbine Engineering Hand Book updates the book to cover the new generation of Advanced gas Turbines. It examines the benefit and some of the major problems that have been encountered by these new turbines. The book keeps abreast of the environmental changes and the industries answer to these new regulations. A new chapter on case histories has been added to enable the engineer in the field to keep abreast of problems that are being encountered and the solutions that have resulted in solving them. Comprehensive treatment of Gas Turbines from Design to Operation and Maintenance. In depth treatment of Compressors with emphasis on surge, rotating stall, and choke; Combustors with emphasis on Dry Low NOx Combustors; and Turbines with emphasis on Metallurgy and new cooling schemes. An excellent introductory book for the student and field engineers A special maintenance section dealing with the advanced gas turbines, and special diagnostic charts have been provided that will enable the reader to troubleshoot problems he encounters in the field The third edition consists of many Case Histories of Gas Turbine problems. This should enable the field engineer to avoid some of these same generic problems
