Hello Clayarter:
I've been lurking long enough! Such a great educational and inspirational
resource. I enjoy the entire spectrum of the Clayart interaction.
Now for my first question. I need to know the BTUs per cubic foot of
natural gas. Just can't find it in any of my references.
By the way , my name is Michael Redwine . I live in Eugene , Oregon and
have been working in clay since the mid seventies.
I don't have my own e-mail address but gratefully can use my friend's ,
Tara, forever!
TIA Michael Redwine

You can usally, and I suggest you do, call your gas supply company and ask
them. They can give you a good average of what it is run BTU/cubic foot.
The btu content can very great form area to area. At my studio it run about
1400 btu per cubit foot, very high. Most gas applance are made for 1000 to
1100 btu/foot.

Michael,
"Although natural gas varies slightly in its composition from one part of
the country to another, its average heating value is 1025 Btu per cubic feet.
To release this full Btu potential, the A/F ratio should be 10 cubic feet of
air to 1 cubic foot of gas."

On average natural gas has approximately 1200 Btu's per cubic foot at 10
inches of water column pressure. NL

The gas industry long ago decided that 1000 Btu/cubic foot was the proper
amount of energy content on which to base prices and contracts. There
usually is a allowance/tolerance of 10% leaway, up and down; if down,
there is a lower price penalty, if up, there is a price bonus that the
seller receives from the buyer.
It is routine that pipeline gas is analyzed daily (or more often)
for Btu content and the bill for the gas sent that day adjusted
accordingly.
Pure methane would have a Btu content of 1000 Btu/cf, but there
are often contaminants in the gas (carbon dixodie is one) that lower the
Btu level, so the gas company usually adds a small amount of propane to
boost the Btu level.
All this is governed by law and regulation, so the seller is not
doing this because it loves us but because it is obliged to do so.

Michael,
Most folks use 1000 BTU's per cubic foot as the norm for calculating natural
gas output. It does vary slightly though, depending on geographic source. In
the continental North America, gas can vary from 970 BTU/CF in Kansas City to
1123 BTU/CF in Pittsburg.

Hi Michael: Haven't seen you for a while. Fred Olsen says that the BTU
rating for natural gas is 900 to 1150 BTU's per cubic foot and 41,400 per
gallon. Take it easy & get some new reference books. :^)

Michael,
According to the VNR "Condensed chemical dictionary" natural gas has
about 1000 BTU per cubic foot. I expect this is an average value
because the actual make up of natural gas varies depending on the site
mined. It is much less than many other fuels. But is usually very
cheap.
