Expected Behavior

Large Bronze boiler is supposed produce 108 buckets of steam from 100 mb of lava like small boilers

Actual Behavior

Instead it produces 5.6 buckets of steam in 7 ticks

Steps to Reproduce

Put a bucket of lava into a large bronze boiler

So i looked into the fuel efficiency/drain of the boilers in both 1.20 and 1.12 and this is what i got:

Lava as fuel

machine	steam (mb) / t	fuel cycle (t)	steam (mb) / cycle	fuel (mb) / cycle	steam (mb) / fuel (mb)
1.20 Low Pressure Steam Liquid Boiler	12	7200	86400	100	864
1.20 High Pressure Steam Liquid Boiler	30	3600	108000	100	1080
1.12 Low Pressure Steam Liquid Boiler	12	1200	14400	100	144
1.12 High Pressure Steam Liquid Boiler	30	600	18000	100	180
Large Bronze Boiler	800	7	5600	100	56
Large Steel Boiler	1800	7	12600	100	126
Large Titanium Boiler	3200	7	22400	100	224
Large Tungstensteel Boiler	6400	7	44800	100	448

Creosote as fuel

machine	steam (mb) / t	fuel cycle (t)	steam (mb) / cycle	fuel (mb) / cycle	steam (mb) / fuel (mb)
1.20 Low Pressure Steam Liquid Boiler	12	7200	86400	250	345.6
1.20 High Pressure Steam Liquid Boiler	30	3600	108000	250	432
1.12 Low Pressure Steam Liquid Boiler	12	1200	14400	250	57.6
1.12 High Pressure Steam Liquid Boiler	30	600	18000	250	72
Large Bronze Boiler	800	10	8000	160	50
Large Steel Boiler	1800	10	18000	160	112.5
Large Titanium Boiler	3200	10	32000	160	200
Large Tungstensteel Boiler	6400	10	64000	160	400

There are two issues:

Firstly, the 1.20 Steam Liquid Boiler have a recipe duration that is 6 times longer than the 1.12 equivalent (as noted in the fuel cycle column), which makes them 6 times more fuel efficient than they should be.

Secondly, even if adjusted for 1.12 values, the Steam Liquid Boiler are still more fuel efficient than the Large Bronze Boiler and even the Large Steel Boiler when using Lava (the latter being caused by Lava not having a separate recipe for Large Boilers like Creosote does, or the automatic recipe conversion not being balanced correctly).

As it is, the High Pressure Steam Liquid Boiler has 2.4x the fuel efficiency of even the Large Tungstensteel Boiler when using lava as fuel.

yea we know
it's a bug, but there's no good reason to fix it as is because it's useless either way.

I feel like this issue should be a higher priority then it currently is now. As it stands now Steam Age - Lv/Early MV power generation pretty much solely consists of singleblock boiler spam. And in the later tiers steam becomes completely nonviable altogether, although I believe that also is because of other factors but addressing this issue would definitely help.

I have similar issue for creosote

Large Steam Boiler is x8 less efficient then High pressure steam boiler and costs a lot of resources and time (building 25 single block boilers would be slightly more expensive but it would be usable )

I would like to see numbers for creosote for Large Steam Boiler readjusted

As of right now Large Steam Boiler seems to be huge waste of time and resources. When I was building I assumed that its worthy investment (so blame largely on me), but I still feel like I was tricked because I can't really use it
