Advanced Low-Emission Combustion Technologies

Dear Colleagues,

Sustainable combustion technologies are key processes for decarbonizing the energy and mobility sectors in the framework of energy transition. Alternative energy carriers with carbon-free or carbon-neutral fuels from renewable sources, such as H₂, NH₃, methanol and biofuels, are drawing increasing attention due to their features related to net-zero CO₂ emissions. The combustion behaviors of these new alternative energy carriers are different from conventional fuels, especially in relation to their ignition/oxidation times, flame stability, pollutant emissions, etc. Several drawbacks related to the utilization of alternative fuels can be solved with advanced combustion technologies. Advanced low-emission combustion technologies including MILD combustion, oxy-fuel combustion, sequential combustion for GT applications, NOx and SOx reduction, catalytic combustion and chemical looping for new alternative fuels are promising methods.

This Special Issue aims to report on the latest technological advances in low-emission combustion technologies for alternative energy carriers (such as H₂, NH₃, methanol, biofuels and metals) and serves as a platform for experimental and modeling analyses of advanced combustion technologies for low-carbon emissions.

Topics include, but are not limited to:

• Low-emission combustion technologies, including low-carbon and hydrogen-based fuels, MILD combustion, oxy-fuel combustion, chemical looping, and NOx and SOx reduction;

• Reaction kinetics, including the kinetics of hydrocarbons, oxygenated fuels and alternative energy carriers, the formation of pollutants, elementary reactions, and mechanism generation and reduction;

• Laminar and turbulent flames, including experiments, theories and modeling applied to ignition, propagation, extinction/stabilization and instabilities;

• Solid fuel combustion, including fundamental aspects related to pyrolysis, oxidation, gasification and ash formation from coal, biomass and wastes, as well as the combustion of propellants and metals;

• Pollutant emission treatment and abatement;

• Diagnostic technologies, including flow velocity, species and temperature measurements, etc.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
