Good Evening Bill.

I'm not sure if i fully understand what you wrote. But if i understand you correctly, red lines create the actual uptakes, orange are air screens, light blue is a fidley wall right on top of air screen and green is vent shaft supplying fresh air to stokehold fans.



As far as i know the boiler uptakes are some kind of double-layer structure. The actual uptake is inside the steel structure of simillar shape but bigger. The air gap between those 2 structures serves as some kind of 'air insulation' to prevent overheating the surrounding space. Correct me if what i wrote is wrong.

In term of this isometric view - i'm affraid something like this does not exist. I think we would need to create something like this by our own.

Regards,

Karol
