In the joint project "Load and Fuel Flexible Combustion - LaBreVer", the aspects of load and fuel flexibility already started in COOREFLEX are now to be dealt with much more intensively with a view to the energy transition, without losing sight of increasing overall performance. This will lead to a highly networked joint project in which the sometimes contradictory objectives are to be approached in an integrative manner.
Gas turbines are particularly suitable for meeting the increased requirements regarding the instantaneous provision of residual load resulting from energy demand and fluctuating electricity generation from renewable energies. In this market environment, development efforts are aimed, among other things, at increased operating and fuel flexibility, part-load operation up to own requirements (low minimum load operation) and fast load-following behaviour while maximising efficiency and service life at the same time. Improvements in the area of combustion are one of the development priorities.
In the past, the projects of the AG Turbo have made considerable progress in understanding combustion processes, which has made it possible to develop thermoacoustically stable combustion systems with low emissions despite ever-increasing temperatures and energy density.
The focus of LaBreVer is on extending the thermoacoustically stable operating range of the overall burner/combustion chamber system to high and low loads with reduced nitrogen oxide emissions, coupled with the ability to allow a higher hydrogen content in the fuel gas as well as to burn liquid fuels. In addition, the local storage and reconversion of hydrogen into electricity is being investigated as a potential application for hydrogen-capable gas turbines.
