The demand for alternative fuels has increased significantly during the previous decades in
order to reduce pollutants and increase the amount of energy that can be generated from …

In recent decades there has been a strong trend towards the use of lean premixed
combustion in order to produce gas turbine systems that are compliant with air quality …

The objective of this paper is to employ a numerical approach to model a 150kW tangential
swirl burner to investigate the consequence of central air injection on the flashback …

The stabilization of premixed flames within a swirling flow produced by an axial-plus-
tangential swirler is investigated in an atmospheric test rig. In this system, flames are …

Swirl stabilised combustion is one of the most widely used techniques for flame stabilisation
in gas turbine combustors. Lean premixed combustion systems allow the reduction of NOx …

Nowadays, almost all state of the art gas turbines employ swirl-stabilized combustors for
flame stabilization. A strong swirl is imparted on a jet that emanates into the combustion …

This paper first reviews recent ideas that explain why swirl has a strong stabilizing effect on
a flame. Then some measurements are discussed that were obtained using a complex gas …

Combustion with high-hydrogen-content fuels is currently viewed as a potential method for
reducing the output of greenhouse gases resulting from stationary power generation …

Aiming to improve the stabilization of unstable swirling turbulent premixed flames, an
actively controlled swirler and electrical hardware and control software are developed …
