BonoKeram: Increasing the flexibility, efficiency, and economy of gas turbines for power generation by providing components made of monolithic advanced ceramics

One of the main objectives in the further development of gas turbines is to increase their efficiency. The greatest potential for increasing efficiency lies in increasing the turbine inlet temperature and the pressure conditions prevailing within the turbine. Due to their thermal and mechanical property profile, it is currently not possible to achieve a significant improvement in efficiency with metal materials. Components made of advanced ceramics can withstand significantly higher temperatures. Therefore, the overall objective of the project is the production of turbine components made of monolithic advanced ceramics (silicon nitride) and their successful application. The use of monolithic ceramic components allows a new generation of gas turbines for energy generation. Due to the material properties of advanced ceramics, turbine inlet temperatures of up to 1400 °C can be realized without additional cooling. The natural passive layer of advanced ceramics increases the corrosion resistance and allows the use of alternative fuels.
