RE: GAS-L: Aqualux plant blows up!

["Bernhard Kronberger" <bernhard.kronberger@jrc.it>]

Dear gasfifier group,

After the email from Leland, someone might say, that the compared to other
hydrocarbon fuels, low minimum ignition energy (0.02mJ vs. 0.25mJ)increases
the risk of hydrogen applications. Consider that already a weak
electrostatic spark discharged from a human body has an energy level of
about 10mJ and would ignite all hydrocarbons. Additionally, the minimum
ignition energy of 0.02mJ is valid for stochimetic conditions (30% H2 in
air) but is almost similar below 10% content in air…
Real problems are in my opinion that  hydrogen burns with hot, non-luminous
flames and is therefore difficult to detect for human perceptions. It also
may produce suffocation by diluting the concentration of oxygen in air below
levels necessary to support life.

Dear Gasifiers group,
    Hydrogen is less of a problem than other materials such as propane as
hydrogen vents upwardward and dissipates. Hydrogen's combustion range is
quite a bit wider than propane, but dissipates so quickly that the ability
of
it to combust in open space. Hydrogen's flame propagation rate is so fast
that the confined combustion of it produces a substantial explosion.
