Air Blower

Steam-engine sub-machine that pressurises air.

An Air Blower stands in the Cornish Engine's sub-machine cell, two blocks along the engine's axis under the beam, and is the source of blast pressure for the whole hot-blast plant: it injects 144 litres of air a second per unit of the engine's power, at the engine's inlet steam pressure times 0.75, into the pipe run on its side. Blast counts at 2.5 atm, so the engine's steam has to stay above 3.4 atm or the blower falls under the gate mid-blow.

A twin-tub blower cannot reach that pressure at all; this block, on a Cornish Engine, is the only way the mod gets there.
