First Fire in ammonia operation – an important milestone for the WTZ Roßlau!
Initial results on the ammonia project were presented at the 7th Rostock Large Engines Conference and indicate a promising combustion process. This provides the WTZ with an important development tool for research into carbon-free ammonia fuel.
In the AmmoniaMot research project, both ammonia and diesel fuel are introduced directly into the combustion chamber of the research engine at high pressure and burned diffusively. For the basic measurement and the ammonia tests, the engine was equipped with engine components from project partner MAN Energy Solutions. In addition, HPDF injectors from collaborative partner Woodward L’Orange are available for combustion process development. In this injection concept, the ammonia is introduced via 3 external nozzle needles, with servo-hydraulic control and injection pressures of up to 500 bar possible. Fuel conditioning is provided by an HP ammonia module designed by project partner Neptune Ship Design. The advantage of this dual-fuel combustion process is that a full diesel backup is available.
In trial operation, energetic ammonia contents of 90 % could already be achieved. Further development goals focus on improving engine performance and reducing exhaust emissions.
We would like to thank the German Federal Ministry for Economic Affairs and Climate Protection, the project management organization Jülich and the other project partner, the Technical University of Munich, for their support in this project.
