Firstly, careful design is needed to make hydrogen combustion stable, as hydrogen flame propagation velocity is very high — up to seven times faster than natural gas, which may lead to flame ...

The video provides an impression of the challenge yielding safe and stable combustion with hydrogen as fuel. Early in the video, a stable premixed hydrogen flame can be seen under typical gas turbine ...

The incident occurred when a hydrogen-filled balloon exploded during the opening ceremony of Pokhara Tourism Year.

For methane combustion in air at 1 atmosphere the Adiabatic Flame Temperature is 2,328 K or 2055 C. For hydrogen burning in air at 1 atmosphere the Adiabatic Flame temperature is 2,400 K or 2127 C.

Even better, the burners, which are designed to control hydrogen’s sevenfold-faster flame propagation speed than natural gas, can be retrofitted to existing natural-gas infrastructure.

The metal self-ignites, which also ignites the hydrogen gas. This results in sparks and a lilac flame. There is sometimes a small explosion at the end of the reaction.
