Slight necro here...
I haven't used Steam Boilers since the 1.5 packs -- I know about the solid fuel nerf and the fact that HP boilers now burn 20% more fuel than a pair of LP boilers of the same size. What I don't know or recall is how much steam flow you can pull off of a given boiler block.
IIRC, if you wanted to power a bank of 9 steam engines you had to tap 9 boiler blocks with liquiducts (now fluiducts), then you could merge the fluiducts to carry the steam to your engine cluster. Is this still the case?
Further:
Does an HP boiler provide twice as much steam flow per attached fluiduct than LP? E.g. If I put one fluiduct on the side of a LP boiler, and one on the side of an HP boiler, will the LP boiler power one steam dynamo while the HP boiler would power two? Or does the block type (LP or HP) have no bearing on how much steam it will provide?
Thanks for clarifying!
