The Recursive Sequential Combustion (RSC) invented by Combustion Bay One e.U. aims to produce robust lean combustion with excellent performance in terms of combustion efficiency, NOx and soot emissions. It addresses the fuels of the future, among others hydrogen. The audience at EnInnov 2022 will benefit from the latest progress made in the MOeBIUS project.
This contribution presents the RSC technology and the early developments made at early Technology Readiness Level (TRL, currently TRL 2, meaning that the concept’s plausibility was established). It is explained why trapping a permanent hot gases recirculation serves the combustion in a positive manner. The technical adaptions on the burner structure are discussed, and two concepts named discrete RSC sector and constant-section RSC are presented. It is shown why new materials and additive manufacturing are promising technologies that will help to produce the first demonstrators. The paper ends with a detailed CFD investigation of the constant-section concept.
