Steam Boiler calculation, Steam to EU/MJ

[Dentvar]

Edit: Changed Data with the confirmed once from Thread.

Hi,

I´m doing some math about Steam Boiler and the best way to use all the steam to make it EU/MJ. I don´t search for the way with less lost of energie but a way to draw all the steam my boiler generates turning it into EU/MJ. Playing of FTB Ultimate 1.4.7 (1.1.2)

Here the numbers I found in Internet and I based my calculations on. Please check them and tell me if they are right and refill blank ones if you can.

Data

Steam:
1 Steam= 1mB steam

Boiler:
Output = 720 Steam/t

Comercial steam Engines:
Input = 40 Steam/t
Output = 8 MJ/t

Steam Turbine:
Input = 320 Steam/t
Output = 100 EU/t (200EU/t in 1.5.2)

Energie Bridge:
1 Steam = 0,2 MJ
1 Steam = 0,486 EU ( not taking in mind LV/HV transformation)
1MJ = 2,431 EU
1 EU= 0,411 MJ

Liquiducts:

There is no real Input or Output limit for them. Their throughput is near limitless.
But they are limitet in how much steam they can pump out of the Boiler.
Flowthrought = near limitless
unpowered pump limit = 80 Steam/t
powered pump limit160 Steam/t.

Ways to convert steam

1.Comercial steam engines connected to Boiler

To use all the 720 Steam/t I can use 18 Engines and get 144 MJ/t

2.Steam Turbine connected to Boiler

I can setup 2 turbines directly to the Boiler using 640 Steam. The rest 80 Steam I can use with 2 steam engines. Total outcome= 200 EU/t + 16 MJ/t

3.Connecting Bridge to Boiler

To give the Bridge the full 720 steam/t you need 9 unpowered/ 5 powered liquiduct outputs on the boiler and 5 input at the bridge.
Output is 144 MJ/t or 349,92 EU/t

Conclusion

• Steam engines = Equal to energie Bridge in terms of MJ but bridges are less space intensive.
• Steam Turbine =
  • Less effective then convert steam to EU using a Bridge
  • Less effective then convert MJ(from Engines or an other Bridge) to EU.
• Energie Bridge = smallest and most effective option. But feels a bit cheaty.

Note:All this is based on the fact that I have no max input/output for bridges. Also I would like to know if a Iron Valve has a max. Input/output.


Hope you can confirm me this stuff.

IMHO it's completely rediculous that the energy bridge even takes in steam. It completely undermines the part where you have to craft / spend space on machines that actually use steam and turn it into anything meaningful (energy).

What's next, a way to convert to and from GT's helium plasma?

That is a joke.

The RC Steam Turbine has been recently buffed and now outputs 200EU/t

Also Luquiducts do not have a limit of 160 Steam/t, they are in fact near limitless, just depends on how much inputs you have and if they are powered or not.

I will recalculate it then with 200EU/t I understand that the needed input is untouched?

Could you explain the habbit of Liquiducts a bit more in deep to me?

I saw various posts were they said its recomended to put a seperated line to each engine, is this true or can 1 liquiduct supply f.e. 8 engines if connected with the boiler.

You probably saw posts about using gold pipes. A single liqiuducts can easily carry the output of the largest boiler to 18 industrial steam engines. Make sure you have 9 liquiducts connections (leading to the same single duct) on your boiler though, there's a limit on how much a single unpowered duct can get out of a boiler.

 

[Dentvar]

hurray! that will easy up everything alot
2 Turbines at the boiler and just take the EU and with 1 liquiduct consume the rest of the steam in steam engines for some MJ.
Stupid question: How do I power a liquiduct? a redstone engine is enought of do I need a stronger engine?

With powered we mean the output mode where you need to supply a redstone signal for the duct to pump anything. (You need to wrench it once and then you should see an arrow facing to the duct line from the device away)

IIRC the values are as follows, but i could be wrong here:
1 "unpowered" output duct can provide 80 Steam/t
1 "powered" output can provide 160 Steam/t.

So of you put 9 unpowered outputs on your bioler and connect them to one duct line you can easily transfer all the steam to you engines

 

[Dentvar]

oh, so they can output without redstone signal always put a leaver on one side of they hole system. so I would need to bring a redstone signal to every of the 9 outputs at the boiler?

Just to be sure, the amount sucked out at the conexion block to the boiler is limited to 160steam/t (powered) the volumen into the hole sistem is near to unlimited.

Edit: and why its 9?
720/160= 4,5 so I would need 5 liquiducts to get all from the boiler. 9 would be over kill?

It depends on the machine they are attached to. If the machine has an automatic output you don't need a RS signal. For the boiler you would need 9 unpowered outputs or 4.5 (eg 5) powered ones.
A liquiduct can hold 500mB but has a VERY high throughput once filled which effectivly makes it near unlimitied on how much it transports.

And from your maths you see why the default settings from the PowerConverters mod are broken. One should not be able to produce more EU/t with the bridges than with the Item/engine/whatever the mod provides on its own (in this case the Steam Turbine).

 

[Dentvar]

Finally set up the boiler.
Put 2 Stream turbines on it and one industrial steam engine to power the 2 sawmills who recive wood from our storage sistem.
Finnaly didn´t recaclulate if turbines are more efficient with the buff or not, but I don´t realy care. I will have more then enought energy for the moment with it and its looks way better then a bridge with 1001234563454 liquiducts attached.

edit: still losing 60 stream/t but for the moment I don´t care, I´m always on time to replace the industrial stream engine with 2 commercials.

I had been using the 18 industrial steam engine layout before but just discovered this thread and realized that I can covert directly to either EU or MJ without needing engines first.

I don't get why I'm only getting 160 mB/tick from this setup:

It's the same setup I was using to get the steam to the engines--9 liquiducts connected to the boiler. But now it's only given me a fraction of the steam I'm supposed to get. What gives?

OK, from experimenting, looks like I get an additional 160 for each liquiduct I put in to the steam consumer. But this thread is making it seem like I don't need to do that.

 

[Runo]

I think Iquiducts can only output at 160mb/t per connection, but I could be wrong. Try connecting the liquiducts to 5 sides of the steam consumer and see what happens. I know tesseracts need 5 pipe connections from a boiler to max output.

Also, check the bridge charge bar (blue bar at the bottom). If its full, you aren't drawing the power needed to tax the boilers, hence the lower steam IN

BTW, if you switch to tesseracts based on that info, make sure you set the proper send or receive mode. I had one instance where my tesseracts on top of the boilers were exchanging steam in an infinite loop and not providing power.

 

[gusmahler]

yeah, connecting a liquiduct to each side of a steam consumer solves the problem.

But it also means that it's impossible to generate a 512 eu/t line directly from steam. You have to use industrial steam engines first. Because to make 512 eu/tick, you need over 1000 mB/tick, which just can't be transmitted in 5 liquiduct connections.

 

[Runo]

You can use tesseracts to "compress" your stem output since liquid tesseracts are lossless. Hook the tesseracts up on the boiler in send mode, put one between two steam consumers on the bridge. This way you can max steam usage per bridge. I would hook up 5 steam consumers, 3 tesseracts, and one EV producer for one bridge when I used boilers.

The RC Steam Turbine has been recently buffed and now outputs 200EU/t

I would like to edit the data from my first post to let everything clear and not make others read the hole Thread. Therefor I need the confirmation on this buff.

My data refere to FTB Ultimate 1.1.2 and I just connected 2 turbines to a bridge with 1 glass fibre entrance at the consumer and get exactly 200 EU/t.
So1 turbine still give 100 EU/t. Is the buff just for beta versions?

Not Beta but for Minecraft 1.5.2

You have to power the liquiducts at the consumer. If you take a look on the update in my first Post you will see that they have 160 steam/t output on each side of the Consumer if they are powered.(give them a RS signal)
If you use them like in your screenshot, its just 80 Steam/t so you will only be abel to get 400 Steam/t convertet to EU.

It is infact impossible to generate 512EU/t with a singel Bridge. But since you will need a second Boiler for 1000 mb steam/t anyway this shouldn´t be a problem.
The max. Steam input on a singel Bridge is 160 Steam * 5 = 800 Steam. So as a result you can get max. 388,8 EU/t.

 

[Loufmier]

nope. the max input for steam consumer is 1000mb/t

 

[Dentvar]

nope. the max input for steam consumer is 1000mb/t

Oh, so they have a maximum input? Could you tell me were you find the information? So I can add them in the Main post.
Anyway I do not refere to the max. Steam input of the consumer. I was calculating the maximum you can input him using liquiducts. (should have explained this better-_-)
Dunno if with liquid tesseracts you can reach the 1000mb/t but other wise liquiducts are the only way you can input steam in the consumer or do I forget some other way?
