Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

Energy Science &Engineering, EarlyView.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.

Design Approaches for Oxygen Reduction Systems for Warehouse Storage Applications

Fire and Materials, EarlyView.
ABSTRACT Oxygen reduction systems (ORS) are protection systems, with a design protection objective to limit fire spread beyond the point of ignition. Research has shown that the prescriptive design methods, in VdS 3527, EN 16750, and ISO 20338, are not appropriate as prescriptive design methods as they result in insufficient protection levels.

Predicted Thermoacoustic Flame Response at Megawatt Scale in a Near-Stoichiometric Atmospheric Industrial Furnace

Energies
While gas-turbine combustors have received much research attention, the forced response of large atmospheric industrial flames is much less studied. To improve the understanding of thermoacoustic instabilities in industrial combustion systems, the forced

Scale-Resolving Simulation of a Propane-Fuelled Industrial Gas Turbine Combustor Using Finite-Rate Tabulated Chemistry

Fluids, 2020
The scale-resolving simulation of a practical gas turbine combustor is performed using a partially premixed finite-rate chemistry combustion model. The combustion model assumes finite-rate chemistry by limiting the chemical reaction rate with flame speed.
