Abstract
As a promising renewable energy source, hydrogen has garnered substantial attention and has been widely adopted
in various industries. However, the safety concerns associated with its usage have consistently posed a significant
technical challenge, hindering the rapid development of hydrogen-based technologies in the energy sector. To
address these safety concerns and develop effective inhibitory strategies for hydrogen combustion, this study
experimentally investigates the impact of wire mesh and porous materials on the quenching behaviour of pre-
mixed hydrogen-enriched flames for industrial burner applications. A Bunsen burner is employed to generate the
hydrogen-enriched flame, and mass flow controllers are utilised to precisely control the hydrogen enrichment.
Additionally, emission characteristics are analysed for different hydrogen-enriched fuel mixtures, such as propane
LPG plus hydrogen. Key parameters, including thickness, aperture, porosity, melting temperature, and thermal
conductivity, are determined to select meshes and porous materials suitable for industrial burner applications. An
infrared camera with a spectral range of 1-14 µm is utilised for flame detection and verification. The study’s
findings demonstrate promising results in achieving carbon-free emissions by increasing the hydrogen enrichment
percentage for all studied cases. This research serves as a valuable reference for designing hydrogen flame arrestors
that enhance the safety of hydrogen combustion in burner applications and hydrogen transportation engineering.
