#55400, "RE: Funnel Plating " In response to In response to 8 Thu Aug-03-17 01:19 PMby Ralph Currell
Thanks for the illustration. As I mentioned above, I have little information on the internal structure of the funnels so I can't agree or disagree with your interpretation.
Going by photos and the 'Engineering' plans, the lower funnels (i.e. the portion of the funnels between the boiler uptakes and the deckhouse roof) appear to have 10 radial plates, or distance pieces, between the funnel and the casing. I don't know if this was the case for the connection between the inner and outer parts of the upper funnels. Another consideration is whether the inner and outer parts were rigidly connected or if there was some provision for expansion (the inner funnel presumably being much hotter when in use).
These comments of course apply to the working funnels; funnel number four would be quite different internally.
