So, I understand that, in order for industrial steam engines to produce 8 mj/t, there needs to be two separate liquiducts attached to each engine, due to limitations of how much steam can be carried per liquiduct at a time. I also understand that 9 liquiducts are needed on each 36 hp boiler, in order to draw out the entirety of steam available. I have 2 36 hp boilers, at full heat, and only half steam. My engines, of which I have 36 of, are only producing 6 mj/t. Am I missing something? I'm brand new to this and have probably made a few mistakes. Any help would be greatly appreciated.

Um.
(1.4.7) - 36HP boilers produce 720 mB/t of steam. To run an industrial steam engine at full power you need 40 mB/t. This means you can run 18 industrial steam engines off of one 36 HP engine. Your math is correct.
(1.4.7) - Liquiduct throughput is infinite mB/t. Each liquiduct connection (such as the ones from your boilers and to your engines) is maxed at 80 mB/t. This means that one liquiduct output has enough throughput to fully fuel two industrial steam engines. That is one of your misconceptions.
(1.4.7) - By right clicking a liquiduct connection (the ones on your boiler) you switch them to "powered". They are also required to have a redstone signal activating them. I am not sure if boilers output automatically, but seeing as how you have some throughput, this shouldn't be the problem. Just some more FYI.
Your best bet right now would be to:
(1) Use a multi-meter and determine the throughput of steam through a choke point (i.e. all the possible throughput from the boiler will pass through that pipe. Set it up in such a way that you can measure that correctly). If you determine that your throughput is at the rating you want, then you will need to do a bit of playing around.
(2) I am not sure how the programming for industrial steam engines go, but I have encountered this problem as well. Try connecting a few engines first (say 18, instead of 36) to the output of your two boilers and activate them. You should see that they max out @ 8 MJ/t, if the full throughput of the boilers are flowing through the liquiducts. Then connect the other 18, and then activate them as well.
Liquiducts distribute the flow of liquid through any connection equally in an instant, somewhat simulating liquid in a pipe under pressure. This is not an instance where the liquid is disproportionately outputted amongst multiple outputs, as would happen with BC waterproof piping.
Come back and let us know if this works.

You don't need two liquiduct connections per engine, one will do. Try and change mode and give a redstone signal to a couple of the liquiducts on the boiler.
Also make sure that you have sufficient bandwidth on your energy output. If you are sending the power to Energy cells, you will need atleast 3 parallel Cells. And if you don't use all the power, some of the cells might get full and hinder bandwidth.
AFAIK any unused energy per tick flowing through redstone energy circuits will simply dissipate into nothing. If he is using BC conductive piping, he should be experiencing a blow out very soon. I don't think insufficient energy throughput can throttle a system such that it would cause the engines to produce less energy per tick, when supplied enough fuel for its maximum rating.
Each liquiduct (on the boiler, in the lines, and on the engines) say 50 mb/t throughput when scanned with a multimeter, which should be plenty if they use 40 mb/t. This problem doesn't happen if I attach less than 36 engines, each engine I detach adds an additional .1 mj/t to each engine. Am I just not able to keep 36 industrials running off of 2 36 hp boilers at 8 mj/t?
Also, I changed the liquiducts on the boilers to extraction mode powered via lever, and no change.

The consistent, linear-ish reduction of MJ/t per engine suggests that the throughput of steam is being throttled. It means that your system is reaching equilibrium based on the steam supply, rather than it being an issue of the programming.
Mine was a programming issue. For some reason starting fewer engines first, then subsequently starting the rest, even if the throughput of steam matches the total input requirement of all my engines, seems to work. You're just going to have to play around, or do some problem solving. It could be an issue with your set up, which is something you'll need to find on your own.

Apparently, my steam boiler cannot produce enough steam fast enough to keep up with 18 engines, because I've redone the setup as simply as possible: a straight line of the engines. While I did this, The boiler maxed out on steam, and after hooking the engines up initially, they were at 8 mj/t. But slowly and surely, the steam in the boiler went back down to half, and that's when everything jumped back down to 6 mj/t. Is it because I use charcoal from a tree farm as fuel for the boilers? Is 18 the engine number for biofuel boilers? I'm so utterly lost here.
I slap the engines straight onto the boiler. Always gets 8mj for all of them. also it may also work better if the engines don't share steam ducts.[DOUBLEPOST=1386023519][/DOUBLEPOST]
lol lulz
Sometimes, liquiducts can cause throughput issues if there's an unbalanced load. For example the popular 3-tesseract to 2-boiler setup can cause steam to oscillate between tesseract inputs if the total boiler connection rates exceed 720mb/t and you are using all the power. This doesn't effect the power output, but it will cause quite the FPS drop as the liquiducts cycle from full to empty every tick. Its visible on a power converter when you have the tesseracts hooked up to different steam consumers to the same bridge, you'll see them flip between 1000mb/t and 440mb/t rapidly, as well as steam in the boiler constantly dropping below half. Adjusting my setup back to a 9-80mb connections on a boiler from 12-80mb connections increased my framerate by 30.
