Abstract
In order to improve safety for hydrogen network infrastructure, the ignition temperature by hot wire was investigated for different hydrogen compositions in pipelines. The result shows that minimum temperature for ignition decreased with decreasing hydrogen composition. The minimum temperature was confirmed at a hydrogen composition of approximately 10 vol.%. The one of the reasons is supposed that buoyancy force should generate the convection of gas mixture. It was also found that humidity had a little effect on ignition temperature, flame temperature.
