MILD Combustion and Biofuels: A Minireview [PDF]

Energy & Fuels, 2021
Even in presence of the formidable growth of renewable energy sources advanced combustion processes have and will continue to have an irreplaceable role as a driving force for energy market. This is indeed motivated by the same huge amount of energy that can be conveniently stored in the form of energy carriers, made available from the renewable ...

Alcohols as Energy Carriers in MILD Combustion

Energy & Fuels, 2021
Among the liquid fuels supporting the decarbonization of the energy conversion chain, alcohols play a key role. Mainly considered for engine application, their use in stationary systems designed for power generation is receiving considerable attention but requires further investigation.

Experimental Characterization of a Novel Foam Burner Design for the Low-Excess-Enthalpy Combustion of Very Lean Syngas Mixtures

Energies, 2023
In the present work, a novel foam burner design is proposed and experimentally evaluated for operation with highly diluted syngas mixtures. The lab-scale burner consists of a purpose-built, square-shaped, high-temperature-grade stainless steel tubular ...

Modelling paradigms for MILD combustion [PDF]

International Journal of Advances in Engineering Sciences and Applied Mathematics, 2014
Three-dimensional Direct Numerical Simulation (DNS) data of methane-air MILD combustion is analysed to study the behaviour of MILD reaction zones and to identify a suitable modelling paradigm for MILD combustion. The combustion kinetics in the DNS was modelled using a skeletal mechanism including non-unity Lewis number effects. The reaction zones under
