SE0596 : Grinton Smelt Mill flue[img][/img][img]

As I understand it after attempting bit of research on the design of lime kilns, this flue is a fundamental part of the operation of this type of kiln.

"Henry Robinson, a coal and lime merchant from Skipton, designed and patented three new draw kiln designs in the 1860s in which fuel was kept separate from stone in the kiln to avoid contamination of the final product. Fuel was fed into fireboxes on the side of the bowls with heat being drawn into the bowl."

I would think that the side exit at a shallow angle might be to "draw" the heat through the "bowls".

A similar one near Greenhow:-

showing the kiln in the foreground with the flue running uphill to the "chimney" behind. (the flue is considerably forshortened by perspective from this angle)
