mel/ivor, others:
Just like natural clays have water bound to their molecules as
"hydrate" so do hydrocarbons such as natural gas (90+% methane, CH4, plus
small amounts of ethane, CH3CH3, and propane, CH3CH2CH3). Small amounts of
molecular water binds to these hydrocarbons to form "gas hydrates". How
much? It varies as a function of temperature and pressure during the flow
from well to processing plant to user. I have not looked this up in a long
time but from memory the gas hydrate content of natural gas is 1% or less,
of Propane, perhaps 2% and LPG (propane-butane mix) could be 3%.
During combustion, when gas hydrates break up, it is likely that
some "steam-reforming" occurs and some hydrogen and carbon monoxide are
formed, and exist briefly in the kiln atmosphere. Your gas supplier (NG or
Progane/LPG) has to know the specifications of the gas he sells because
the state sets standards for the heat content (Btu's or joules) of the
fuel, and too much gas hydrates could lower the heat content below the
minimum allowed. So, if you want to no how much "water", ask your
supplier, he should know, or find out for you.
Good pots. Bye. Peace. Tom.
