Tuyere
A hot blast intake for the furnace shaft.
The tuyere is a pipe port on the furnace shaft, and the pressure it needs is not a property of the block: it comes from the burden standing in front of it, and it is a threshold rather than a target. A line even a tenth of an atmosphere under that threshold draws no air at all, reading zero supply exactly as an unpiped tuyere would; there is no partial credit for being close.
