Lancashire Boiler
A twin-flue boiler, larger than the iron tier's, for the high-pressure steam band.
A Lancashire Boiler is a single block raised in place through its own build stages, not a multiblock: right-click it with each stage's materials to add the base extension, the flues and the casing in turn. It holds 1200 litres, boils between 200 and 800 litres of water and makes up to 48 litres of steam a second at up to 12 atm. It needs a vent for its exhaust or the fire chokes out, and a line for its steam: held at its 12 atm ceiling with nowhere to push for thirty seconds, it explodes with a four-block radius; opening the man hatch vents it.
It is the entry to the high-pressure steam band that a Cornish Engine draws on; Getting started has the order to build and fire it in.
