OT: Town gas -> Natural gas ?

[Tim+]

Nope. Coal gas was about 2/3rds as dense as natural gas.

I remember it being done in Cambridge as soon as possible as it wasn't so poisonous at town gas. They were worried about the number of students ending it all with their head in the oven;(!..

It from what I remember of it was done very quickly by gangs of fitters.

Mind you how they got all the bits to turn up when the Gasman traditionally came to call and then wasn't seen for weeks whilst getting the bits remains a mystery;!...

I remember it. The process was not dissimilar the the more recent program of replacing gas mains with those yellow plastic ones.

They did a few streets at a time. Gas turned off and what was left in the pipes flared off from pipes in the street. All the appliances were modified with new burners. (if your cooker was too old it was replaced with a slightly newer one). Then that section of pipe purged and the gas back on. A team working on a few street would be a day's work.

They did well to be able to operate an area which had two types of gas in it. They must have known the pipe layouts better than seems to be the case now. I suppose the range of appliences was smaller then and most would have been supplied at some time by the Gas Showrooms.

Which reminds me of the story, must be from about then - guy decides to end it all. After sitting with his head in the gas oven for an hour, he gives up, and has a cigarette...

Are you sure it's not the other way around ? Natural gas burns with a blue flame. Yellow would imply the presence of another element.

[Clive George]

What colour are the flames in a coal-effect gas fire?

What colour is the flame in a bunsen burner with the air thingy shut?

[Tim Streater]

The colour has to do with the gas/air mix. Either gas should burn with a blue flame if the amount of air mixed with it is correct. The amount needed, however, is probably different for the two types of gas.

Did you never use a Bunsen burner?

[Andrew Gabriel]

Are children allowed to use them nowadays? I bet they don't stand them on asbestos mats. Can you even have gas taps in a classroom nowadays?
