Welcome to CleanAir 2023

Welcome to the official website of the 15th International Conference on Combustion Technologies for a Clean Environment. The Conference will be held at Instituto Superior Técnico, Lisbon, Portugal, from June 25 to 29, 2023.
The conference will address topics such as reaction kinetics, pollutant formation and control, combustion diagnostics, computational methods, turbulent combustion, heterogeneous combustion, stationary combustion systems and environmental impact, engine, gas turbine and spray combustion, gasification, pyrolysis, CO2 capture processes, new combustion concepts, and fire research. 

Lisbon is the capital and largest city of Portugal. It is built in 7 hills and although it has more than 20 centuries of History, is ageless. Beautiful and unexpected colorful views are found at every turn down and it is surrounded by Tagus river and a beautiful coastline.

Professor Mário Costa passed away on the 3rd of June 2020.
As a tribute to his memory and acknowledging his contributions to the scientific and academic communities, we decided to organize the 15th International Conference on Combustion Technologies for a Clean Environment.

Presentation Guidelines

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.

Special Issue

Special Issue


A number of extended abstracts/papers presented at the Clean Air 2023 conference will be selected for recommendation for submission in a special issue of the journal FUEL. Upon submission, the reviewing process will follow the normal procedure.
