Summary

In this paper, results are presented on the development of a coal fired precessing jet burner. The jet precession phenomenon creates unique flow structures within the flame and results in fundamentally new flame aerodynamics and fuel-air mixing regimes. The experimental work was performed at the International Flame Research Foundation in the Netherlands. Results show that using jet precession in a coal burner configuration can significantly enhance fuel-air mixing in a fundamentally new way and can result in significantly reduced NOx emissions. Further planned development work is also discussed in the main text.
