@Juan An interesting read, this could also be recycling in its very base level ...... Thank you for sharing. Cheers Pete
Unbelievable .. Well it is history ... No one minded then .. so why should we amazing when you think ..
Sheffield (UK) had 84 between 1914 and 1935. The article in that link suggests around twenty remain and are Grade II listed. There was one still working on a street near me when I lived in the Crookes area of the city in the early 70’s. John
Nice! i can't understand if the gas is pressurized to the lamp (I guess so) or if they work with the actual pressure from the sewer.
Am guessing that the fuel is piped gas, and the air supply for combustion comes directly from the sewer.
That is nice. I would say the gas was not deliberately pressurized. Just the natural methane build-up that was present at any one time. Would be interesting if they could still work as they once had.
I had a brief look on the patents. See the espacenet. In my opinion the gas flames (burning regular citygas from the gas main) create a draft in the lamp post which is connected to the sewer pipes. Thus the draft "vents out" the sewer gasses which then are led to the gas flames and burnt there. I did not have the time to read the complete patents so far. Erik
That is correct. They were erratic when run only on the unwanted gas, they kept going out. They were soon converted to run on town gas taking in unwanted gases as they arose.
