Oxygen enrichment studies in hydrogen-natural gas burner: A pilot-scale study on emissions and thermal performance

Measurement: Energy
Decarbonising high-temperature industrial furnaces requires efficient and low-emission combustion strategies. Hydrogen and oxygen enhanced combustion (OEC) are promising alternatives to conventional air-fuel systems, but their combined impact on heat ...

Distribution of trace elements around Syowa Station(II) Trace metals distribution in Langhovde

Antarctic Record, 1977
Trace metals (Cu, Fe, Mg, Mn and Zn) concentration distribution in water and sediment were determined by atomic absorption methods with flame and flameless systems using wet dissolution method. The samples were collected from Langhovde, Antarctica.

Combustion Mode and Reactivity of Methane Fuel in Hot O2/CO2/N2 and O2/H2O/N2 Coflows in a Nonpremixed Small‐Scale Tube Burner

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The reactivity of methane fuel was numerically studied to compare the effects of CO2 and H2O dilution of hot oxidizer atmospheres on combustion modes and flame characteristics. A nonpremixed small scale burner at 8.6 kW thermal load forming central fuel jet flame in coflow oxidizer atmosphere was employed.

Hunger

Anthropology and Humanism, Volume 49, Issue 2, Page 172-178, December 2024.
Summary This piece uses narrative forms from both Black horror and Fantastic literature to grapple with questions of haunting, grief, life in proximity to death, and uneven distributions of access and wealth within global capitalism. The blurring of the lines between the real and the surreal, typical of Fantastic literature, parallels the blurring of ...

A dimensionless modeling framework for scaling flameless combustion furnaces: Integrating energy–exergy and flow-similarity analyses for predictive, low-emission, and scalable industrial design

Results in Engineering
Flameless combustion offers ultra-low emissions and high thermal uniformity, but scaling such systems from laboratory to industrial applications remains challenging due to complex interactions between flow, heat transfer, and chemical kinetics ...

Organizational sensemaking during curriculum implementation: The dilemma of agency, role of collaboration, and importance of discipline‐specific leadership

Science Education, Volume 108, Issue 5, Page 1448-1473, September 2024.
Abstract Adopting new instructional materials is an important way to support reform in science education, but implementation can be challenging and complex. Therefore, we conducted a contrasting case study of two middle schools implementing new curricular materials.

Potential of Aluminum as a Metal Fuel for Supporting EU Long‐Term Energy Storage Needs

Advanced Materials Technologies, Volume 9, Issue 15, August 7, 2024.
In this manuscript, Barelli et al. evaluates the long‐term energy storage (ES) needs associated to the EU's energy transition and proposes an innovative approach based on aluminum as a green energy carrier with high volumetric energy density. Abstract The EU's energy transition necessitates availability of green energy carriers with high volumetric ...
