Unraveling the impact of CO2 exhaust gas recirculation on flame characteristics and NOx emissions of premixed NH3/DME swirl flames

open access: yesApplications in Energy and Combustion Science
The low combustion intensity and high NOx emissions of ammonia (NH3) pose challenges to its applications in energy and power devices. Co-firing strategies with reactive fuels, such as hydrogen, methane, syngas, and dimethyl ether (DME), have been ...

Drivers and barriers to the diffusion of energy-efficient technologies—a plant-level analysis of the German steel industry [PDF]

open access: yes, 2017
The paper aims at explaining why large-scale energy-intensive industries—here the German iron and steel industry—had a period of slow uptake of major energy-efficient technologies from the mid 1990s to mid 2000s (Arens and Worrell, 2014) and why from the
