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.
