Flame Ignition Limits: Ignitable Gas Envelope Considerations
The ignitable gas envelope is importantto establishing separation distances forunintended releases of hydrogen.
The extent of the ignitable gas envelopecan be based on several criteria. Which is best for Codes & Standardsdevelopment?
For example:
Time-averaged H2concentrationfield reveals extent of cloud withintraditional flammability limits (4% LFLto 75% RFL).
Do traditional (static) flammabilitylimits provide a suitable measure ofignitability in turbulent flowingsystems?
