Current UK policy aims to replace the old coal fired Power Stations with new and higher efficiency gas stations by 2025. As large coal stations edge closer to closure there will be more emphasis on the availability and performance of, combined cycle gas turbine (CCGT) stations, which is essential to ensuring safe and reliable generation in the UK during the transition to a low carbon economy. For the plant operator, there are increasing pressures to ensure that any capital or operational expenditures on operating plant are fit-for-purpose, recognising material age, condition and operating regime.
The proposed research in this Engineering Doctorate (EngD) project is aimed at utilising the plentiful supply of in-service site metallurgical/inspection and operational data to improve the predictive capability of current life assessment models. The ultimate aim is to develop ’point of application’ material models that can seamlessly use site metallurgical/inspection and operational data from the station to provide the operator with a timely and predictive life assessment capability. It is anticipated that this research will involve developing modified creep and creep-fatigue models that utilise data such as surface hardness and creep replicas and likely coupled to results from miniature specimen tests. In addition, site operational data will be used throughout to support the development and demonstration of predictive computational models. The project will focus on the application for Grade 91 steels which are used extensively in CCGT heat recovery steam generators (HRSG’s) and associated high temperature pipework systems.
The Engineering Doctorate (EngD) is of four years duration and carries an enhanced annual stipend of £19,053 to eligible UK candidates. Please visit our web site to find out further information on the Centre. http://www.ccscfe-cdt.ac.uk/
