This is interesting in the fact that the system of using pipes such as these for a chimney was used at Talybont (nr Aberystwyth). In 1868 George Green of the Cambrian foundry installed a 5 h.p. steam engine in an "upper adit". My opinion is that this adit was Myddeltons Adit which cut the western engine shaft. There is a complete collapse there today running all the way down through the workings, but a section of pipe, sooty on the inside remains, as does a small pile of ashes and rusty metal fragments. The pipework would have course been carried up the engine shaft to day.
I am of course familiar with Minllyn, as I do travel around, but have not seen anything like this elsewhere. Has anyone else?
