i tested the mod in creative and notice that if you have mekanism install that mod is seeming to override the reactor forcing it to make liquid steam which the turbine won't accept as fuel

i see two ways to fixes this
allow liquid steam as steam in turbine or only allow reactor steam to fill the reactor steam slot in which after the pipes will move it to the turbine

while i do know a bug already submitted would do
i have submitted bug with the same similar problem already submitted before however the devplor seems to never seems to it

i went this way because the problem is so big it needs to be heard

i know if you want to make it useful just add your own pipes

Thank you for the report.

Let's start with some definitions. When you talk about "liquid steam" what do you mean? A Fluid (in Minecraft / Forge terms) as opposed to a (Mekanism) Gas?

The Turbine you mentioned is my own or the one from Mekanism? What type of fluid ports did you use to connect the two?

no this steam comes from mekanism
i took that mod out and the reactor work fine put it in so and broke again it's possible it's tag as steam leading to the confusion of the reactor but it isn't tag for the turbine witch means nope
and note right now it's the only mod that will transport your steam so sorry
you two mod owners are going to have to work it out together to fix the problem sorry i don't know much

Could you please answer my questions?

What type of Fluid Ports are you using and for doing what? Are you trying to pump steam into an Extreme Reactor Turbine or a Mekanism Turbine ?

Also, what version or ER and Mekanism are you using?

A Reactor always generate "liquid steam" (as opposed to mekanism gas steam) or, more precisly, the Forge Fluid associated to the vapor being generated inside the Reactor. A Gas steam cannot exist inside the Reactor

If your coolant is "water" it will be vaporized into "steam". A random fluid tagged as "steam" will be choosen as the steam fluid when the first bit of water is vaporized inside the Reactor, it does not matter what mod it belong to as long as it is a fluid and it's tagged as "steam"

The Forge Fluid Port will emit fluids, so you need a pipe that can handle Forge Fluids.
The Mekanism Fluid Port convert forge fluids to Mekanism Gasses (using one of Mekanism Rotary recipies) and you need a pipe that can handle Mekanism Gasses to transfer it

My Turbine only accept forge fluids so you need to connect a Forge Fluid Port from the Reactor to a Forge Fluid Port on the Turbine. As long as the fluid being inserted is tagged as "steam" the Turbine will accept it. It's not possibile to insert a Mekanism Gas Steam into my Turbine

then that is the problem maksim doesn't transport the fluid without changing it to their type of gas in which the turbine does not accept it
the now makes steam : which the game think is a gas
the turbine will not accept it and i don't know how to make it accept it that is the problem
well
and i know of no mekanism gas turbine or reactor
ER : 1.16.4-2.0.12
Mek : 10.0.18.445
ports don't seem to be the problem (every port will output it and the special mekanism ports will connect to a pressure pipe which is a gas pipe )

the reactor steams to be going crazy first liquid stem now steam
here are the pictures if you want them
the liquid steam and steam i think is from mek
i believe yours is water vapor
because the condensing unit will work with the steam
but your turbine will not
it will still pump out

I'm sorry but I stil don't understand what you are trying to do.

If you want steam for using it in an Extreme Reactor Turbine you have to pump the steam produced by an Extreme Reactors Reactor: use a Forge Fluid Port in output mode in the Reactor, connect to it a pipe that can handle fluids (not gasses!) like the mechanical pipes from Mekanism for example, connect the other side of the pipe to a Forge Fluid Port in the Turbine. You could also pump water out of the Turbine and back into the Reactor in the same way, just switch directions on the ports.

If you want steam in GAS FORM for using it in Mekanism machines or in it's Industrial Turbine you need to use the Mekanism Fluid Port in the Reactor. That port will convert steam in fluid form to steam in gas form. Use a pipe that can handle Menanism gasses, like the Pressurized Tubes from Mekanism.

the problem solved itself mekisan now requires 1.11 forge only 1.7 is available so no bug any longer but that also means your mod is partially useless

You do known that this make even less sense that what you posted before right?
