The topics of the conference include but are not limited to:

• Combustion fundamentals

• Reaction kinetics

• Combustion diagnostics

• Computational methods

• Laminar flames

• Turbulent combustion

• Droplets and spray combustion

• Solid fuels combustion

• Pyrolysis and gasification

Presentation Guidelines

ORAL PRESENTATIONS

The time allocated for the presentations is 60 minutes for the invited lectures and 25 minutes for oral presentations, including the time for discussion. Laptops connected to LCD projectors are available in all rooms. Speakers should bring their presentations on a USB flash drive in Microsoft PowerPoint format (*.ppt, *.pptx) or Adobe PDF format. The presentations must be delivered to the local staff and copied to the laptop of the room allocated to the presentation. First day presenters should deliver their presentations during the morning coffee break on Monday, June 26th. All the other presenters should do the same by the end of the previous session, even if the scheduled session is on the following day. Speakers may also connect their laptops directly to the projectors, but we cannot guarantee compatibility.

POSTER PRESENTATIONS

Posters must have A0 format (841 mm x 1189 mm, upright format - vertical). They must be placed in the poster panels during the coffee break before the poster session (Wednesday, 28th June, at 11:15-11:35). The organisation will provide pushpins to attach your poster on the poster panels. We kindly ask you to use them and not any other kind of material as they might cause damage to the panels.

Green iron and aluminum as recyclable energy carriers in circular economy - From global opportunities to solid fuel combustion physics

Read Abstract

Green iron and aluminum as recyclable energy carriers in circular economy - From global opportunities to solid fuel combustion physics

Abstract:

The transformation to a net-zero carbon society is one of the most pressing challenges of our time. Green metal fuels, produced from metal oxides using renewable energy, are emerging as a carbon-free, high energy density replacement for fossil fuels due to their availability and recyclability. Iron and aluminum in particular iron and aluminum are promising options for a carbon-free cycle since they are non-toxic, safe to transport, easy to store, abundant, and in principle can be recycled an unlimited number of times.

This plenary will deliver two key messages:

1. Iron and aluminum are promising carriers of renewable energy for a net-zero carbon society.

2. While previous work on solid carbonaceous fuels provides an excellent starting point for studying metals as energy carriers, the physics of iron and aluminum combustion is quite different, fascinating, and largely unexplored.

In the first part, iron and aluminum are introduced as a recyclable chemical energy carrier. During the reduction of metal oxides, energy from renewable sources such as wind, hydro, and solar is stored. This energy is released again through combustion in air or steam. This yields either high-temperature heat (air) or high-temperature heat and hydrogen (steam). The product of this zero-CO2 combustion process is solid metal oxide. One promising application of metals is the retrofit of existing infrastructure. This is demonstrated with a thermodynamic system analysis for a coal-fired power plant to be operated with iron powder in the future. This is followed by a techno-economic analysis, for which different partner countries for reduction and oxidation are considered. Hydrogen and iron are compared as energy carriers based on round-trip efficiency and levelized cost of electricity.

In the second part, selected experimental and numerical results on the combustion physics are presented. First, the oxidation of single iron particles is showcased, and the different phases of ignition and combustion are discussed with a special focus on the coupling of gas phase transport with the condensed phase kinetics. Similarly, the fascinating physics of aluminum-steam combustion are explored. Going towards multidimensional flames, discrete and continuous flame propagation modes are analyzed. Finally, results for turbulent iron-air flames are presented. The need for well-controlled and well-characterized experimental conditions to reduce uncertainties is demonstrated by comparison to simulation results.
