Pinging indicates that the fuel is below the rated octane level. Sounds like a case for the local consumer fraud authorities, if they have not been legislated away in your location.
Those organizations are often not very useful, they won't do much. I've sometimes filed with such agencies before, was a waste of time.

It *isn't* propane. Natural gas is mostly methane.

The components vary depending on source. There is almost always _some_ propane.

Trace amounts? It can be 20 % out of the ground before processing, and is typically about 1% on delivery to residential customers.
And perhaps there are other components as well. The gas in NL is quite good but I've heard rumors they are going to mix it with lesser quality gas from Russia so a lot of boilers and furnaces will need changes.

We just don't bother to adjust those clocks after a power failure.
Get a Japanese car with electronics from Denso :-)

Some of the reports I have read say the super efficent coal and gas plants are up to 60% and the transmission losses are 6-8%. The transmission loss number seems low to me. Anyone know for a KW generated at the plant what can be expected at the service entrance to the meter?

I looked those up recently. Avg. price in January 2009 was $1.85. (AAA). T'was a little over double that in March 2011, peaked at $3.98 May 6th, 2011. Price in the U.K. was US $8.50/gal, March 2011.
Mostly tax, right? (raw materials and processing cost roughly the same everywhere)

I think in the US it's around 93-94%, your transmission loss number sounds about right.

Our residential NG prices vary depending on content. The meter reading is adjusted for calibration and then again depending on what they are piping us that month, so the bill reads in "Therms".
Gas used to be well below the national average here. Now it's just a little below.
Yepper!
?? I don't think that's even possible theoretically based on the Carnot cycle with realistic hot and cold temperatures.
According to these guys, the world _average_ for coal plants is only
28% efficiency, and the most efficent plant in the world (in Denmark) is only 45% efficient. I would imagine the US is between Europe and the developing countries in the average efficiency.Best regards, Spehro Pefhany

Integrated coal gasification lets you start off by burning the gas in a gas turbine, which pushes up the "hot" temperature quite a bit, but your web-site doesn't have this pushing up the efficiency higher than
50%. If the waste heat from the station is used for community heating, the cold temperature goes down a bit, and the efficiency calculations may give the power station credit for all the energy it ships out as low-grade warmth, rather than just that fraction that could be used to generate electricity, so 60% efficiency may not be impossible.I'd suspect that the US would be worse than Europe - district heating is only economic if the power station is close to the centre of a densely populated city. US population densities outside of places like New York aren't high, while Nijmegen - with a population of about
150,000 apparently does (IIRR) have district heating in the suburbs close to the power station.-- Bill Sloman, Nijmegen
