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?
