Combustion is a reactive oxidation process that releases energy bound in chemical
compounds used as fuels─ energy that is needed for power generation, transportation …

Chemical energy carriers are crucial for addressing challenges that arise from time lag,
large distances, and temporal fluctuations in renewable energy production, which lead to …

Micrometric spherical particles of iron in two narrow size ranges of (38–45) µm and (45–53)
µm were injected in a bench scale, transparent drop-tube furnace (DTF), electrically heated …

Metals can serve as carbon-free energy carriers, eg, in innovative metal-metal oxide cycles
as proposed by Bergthorson (Prog. Energy Combust. Sci., 2018). For this purpose, iron …

In the present study, a novel and initiative approach towards a self-sustainable metal
combustion burner called the “Metal Cyclonic Combustor (MC 2)” is introduced. The results …

In the present study, a novel in situ particle sizing approach is proposed and used to
measure the characteristic timescales of micron-sized iron particle combustion under low …

In this work, we use a boundary layer resolved model to improve a Lagrangian point particle
model to simulate the combustion of single iron particles. By resolving the full boundary …

This manuscript reports on the combustion of powdered iron, for the purpose of utilizing it as
an environmentally friendly circular energy carrier. The conducted research investigated the …

Iron and its oxides have been proposed as energy carriers for a carbon-free, circular energy
economy. Focusing on the energy release step of the cycle, this work is concerned with the …

Metal powder is a promising carbon-free and recyclable energy carrier. Direct combustion of
the micron-sized iron particles involves complex physical and chemical processes, such as …
