Can someone explain me why this setup i can't go over 155°celcius?

Alguém pode me explicar do porque desse setup eu não posso a cima de 155 graus célsius?

the temperature sensor that opens the heat injector door is configured to that temperature

If a set it up over 155°celcius the steam turbines start to overheat it

not if you properly cool them

im cooling them using petroleum.

 

[SGT_Imalas]

petroleum is a bad coolant and likely insufficient here, try water, nectar or PWater instead

hm thanks i'll try it another coolant then

For future reference, the steam turbine converts 90% of the absorbed heat into power, the other 10% heat up the turbine itself. Higher steam temps give more power, but also require more active cooling.

Aquatuners reduce the liquid temperature by 14 degrees flat. This makes the actual heat energy amount thats removed from the liquid coolant dependant on its SHC. Liquids like petroleum have a very low shc, making them inefficient for AT cooling because they only remove comparably small amounts of heat energy from the coolant.

Liquids like water, pWater or nectar have a very high SHC, making aquatuners a lot more efficient by removing a lot more heat energy from the coolant

To clarify, petroleum is a bad coolant for aquatuners because aquatuners cool by a constant temperature.  That means you want a coolant that has the highest possible specific heat capacity.  Specific heat capacity is the measure of how much energy it takes to change the temperature, or conversely how much energy is transferred with a change in temperature.  Higher is better on specific heat capacity when it comes to aquatuners, as said by SGT_Imalas.

While petroleum is a bad coolant for aquatuners, it is a good coolant for metal refineries.  That is because metal refineries add constant energy rather than temperature to the coolant.  That means that the energy added to the coolant is constant, it does not change depending on the liquid.  It does mean that the temperature change of the petroleum will be higher, as lower specific heat capacity means that you will get more temperature change per joule (or DTU I guess) of heat energy.  But you don't lose energy or efficiency, so the higher boiling point is better because you can run the petroleum through a steam room to dump the excess energy.
