DSC can be used to determine the enthalpies of formation for the 3d transition metal oxalates

Chemical Thermodynamics and Thermal Analysis, 2022
Differential scanning calorimetry has been used to measure the enthalpy of formation for manganese, iron, cobalt, nickel, copper and zinc oxalate. By adding a flameless combustion catalyst (CuO) and using scans of 2 K min−1 in static air, the values ...

Chemically Self‐Powered Pre‐Activation Strategy for Catalytic Purification of Lithium‐Ion Battery Thermal Runaway Off‐Gas

Battery Energy, Volume 5, Issue 4, July 2026.
The catalytic oxidation method is employed to purify lithium battery thermal runaway fumes. Superoxide (e.g., KO2) provide heat to activate the catalyst, while a blower supplies oxygen and regulates temperature, achieving a safe and efficient purification process with hydrogen and carbon monoxide removal rates exceeding 87%. ABSTRACT During lithium‐ion

Energy‐Efficient Combustion Technologies and Burner Designs for Glass Melting Furnaces

International Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Glass production is one of the most energy‑intensive manufacturing processes, requiring furnace temperatures above 1600°C. These temperatures depend on burners that must balance thermal efficiency with emission reductions. This article reviews the development of combustion systems in glass furnaces, focusing on their impact on energy ...

Emission Modeling of an Interturbine Burner Based on Flameless Combustion [PDF]

Energy & Fuels, 2018
Since its discovery, the flameless combustion (FC) regime has been a promising alternative to reduce pollutant emissions of gas turbine engines. This combustion mode is characterized by well-distributed reaction zones, which potentially decreases temperature gradients, acoustic oscillations, and NO x emissions. Its attainment within gas turbine engines
