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.

MILD combustion of methane in a model combustor with an inverse-diffusion flame configuration [PDF]

, 2022
MILD (moderate or intense low-oxygen dilution) combustion is a promising technology for mitigating NOx emission from fuel combustion, but the combustion stability becomes an issue when using low-preheat air due to the slower reaction at the burner exit ...
