Energy crisis

[Saigon]

To most people over a certain age natural gas is the methane in the piped supply as opposed to town gas

You are probably right.

I worked for BG for 18 years, and offshore for 25. I remember my mate losing his eyebrows to methane when it switched from town gas! lol

I beg to *** differ, old son. Mine does.

I believe noxious fumes are a slightly different kettle of fish to 'gas'.

But, coincidentally, a very similar smell, at times, to a kettle of rotting fish.

We bow to your greater knowledge of rotting fish recepticles.

One might reasonably argue that @dem maser is more intimately familiar with such things.

What do you want to know?

I take it that I'm better off with an electric boiler than a gas one these days then ?

No!!!!!! Even in these crazy energy price time gas is circa 6p kWh electricity is 27p kWh.

I think that should answer your question?

Nothing that would make me feel unwell. So, on this topic, probably nothing!

oil is the way to go.

Always use lube...

Electric boilers must use less kwh than gas then surely ?

It takes the same amount of energy to heat water whether that energy is derived from gas or electricity. The question is efficiency.

Gas Boilers are around 90%, electric 99%. ie the amount of heat derived from a gas boiler 900W goes into heating the water and say around 990W from electric. Some people say that electric boliers are 100% but the outsides are hot therefore there must be some losses.

As the heat is lost into the heated envelope (the house) some people would be right.

Not quite zero admittedly

Pure methane is odourless. The gas that comes out of the well isn’t pure methane and that’s the odour you’ll smell. How pure the gas you get in your house will depend on where it’s come from but it’s as pure as they can get it otherwise it’ll start to soot up burners etc.

Natural gas on the grid is controlled via Wobbe index value. Calorific value measured in Mj/Sm3.
Rule of thumb the higher the methane content the lower the calorific value, the heavier the components and higher carbon number the more CV it has by volume. We measure composition C1 Methane through to C10.
Terminals blend gas purely to control the Wobbe index. Being outside the Wobbe index values causes problems with things like combustion, flame out, excess CO, soot etc.

Mj/Sm3

What on earth are those units?

C

C

Megajoules (should be Capital J for James Joule of Salford) divided by something (S)cubic meters...I think...
