A visit that was worthwhile for everyone: Under the motto \u201cThe future of the steam turbine against the backdrop of energy policy\u201d<\/strong>, solutions for the upcoming challenges, such as the increasing importance of combined-cycle gas and steam power plants, increasing demands for flexible operation and the associated adjustments on the manufacturer and operator side as well as in the entire service sector were presented and discussed.<\/p>\n

In addition to the selected lecture programme, the focus of this this year\u00b4s conference was on professional exchange, which was stimulated by a panel discussion and themed caf\u00e9s on various specialist topics.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In the panel discussion on \u201cThe future of steam turbine development and utilisation\u201d future applications and potential uses for steam turbines were discussed. The participants in the discussion, who covered the entire spectrum from low-pressure small steam turbines to industrial steam turbines and large-scale power plant turbines, also dealt with the utilisation of hydrogen. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A topic that was also addressed in the lecture programme by Frank Cornak et al. in his paper \u201cCleanSteamBooster \u2013 Fast direct-steam-generation with hydrogen for flexible steam turbine operation\u201d. The paper presented the development of a direct steam generator that generates or heats steam by burning hydrogen with pure oxygen in a stoichiometric ratio. This type of vapour generation is not only CO2-free, but also free of nitrogen oxides. In the already advanced and promising test campaigns, a technology level is to be reached that will enable a prototype to be tested in an existing power plant for the provision of control energy in the next development stage.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In the high-calibre lecture programme with international participation, various concepts were presented in order to meet future requirements. These included, for example, a report by an operator on the challenges of the energy transition, approaches to operation and optimisation at partial load and a presentation on grid stabilisation with synchronous couplings.<\/p>\n

The use of artificial intelligence (AI) was also part of the programme. In his presentation \u201cDeployment of artificial intelligence\/machine learning for monitoring and prognosis of heavy rotating equipment\u201d, Markus Ahorner presented the basics of using AI for predictive maintenance. Four elements are used: machine learning, black box theory, sensor virtualisation and trend forecasting.<\/p>\n

Another topic was analysing availability with the vgbe database \u201cKISSY\u201d<\/a> and practical service solutions for reducing unavailability.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The presentation by Mark Andre Schwarz on \u201cCurrent developments in blade technology taking into account new applications in the energy transition\u201d deserves special mention. Blade developments were presented that are used for the deployment planning of turbomachinery (compressors and expanders), in storage technologies with liquid air (LAES, Liquid Air Energy Storage), compressed air (CAES, Compressed Air Energy Storage) and CO2 batteries. As the expanders are used with fluids other than vapour, there are different requirements for thermodynamics, fluid and blade mechanics, among other things. Accordingly, new blade families have been developed across the entire flow path. However, the classic application, i.e. the steam turbine pressurised with steam, was not ignored, thus considerable efficiency potentials can also be exploited here in some cases. T he paper was particularly well received and was the subject of lively discussion.<\/p>\n

Other contributions provided an insight into additional current topics relating to steam turbines, such as a contribution on the phenomenon of tilting segment flutter or the repair of rotor damage caused by stress corrosion cracking.<\/p>\n

An innovation at this year’s steam turbine conference was the themed cafes with the following topic groups<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
