Towards a sustainable hydrogen economy: the emission of NOx by the combustion of natural gas premixed with hydrogen (06911)

Project nummer: 06911

Omschrijving van het onderzoek

The emission of nitric oxides (NOx) in the Earth's atmosphere forms a major environmental problem. The main source of nitric oxides are combustion processes. At the same time, it can be stated that combustion will remain the key process for energy and heat production for many decades to come, even if expectations concerning the future development of sustainable energy sources are fulfilled. Improvement of the efficiency of combustion processes (reduction of CO2) and reduction of emitted pollutants (NOx, CO, particulates, etc.) is therefore of utmost environmental and economical concern.
In industry a number of (commercial) CFD codes is used to design equipment or understand the combustion processes. However, these lack an accurate prediction of NOx formation processes and they are certainly not validated or suited to predict the influence of hydrogen addition. The chemical model to be developed in this project can directly be implemented in a large number of the existing numerical codes used for modelling combustion. The benefits for the users will be:
1. The possibility to study numerically the implication of hydrogen addition on the NOx emissions of new and existing equipment or systems, like gas turbines, central heating units, and industrial heating processes.
2. With the aid of the model, NOx reduction strategies can be implemented.
