Actually people would love to run the reactor at 500°C or as close to it as possible. It has to run a lot hotter though for maximum power generation. You never want it to hit 1000°C but anything below that is fine. The closer your heat exchangers are to your reactor the cooler it can run leaving a bigger margin for when not all energy is consumed. Why?zOldBulldog wrote: ↑Mon Apr 29, 2019 3:20 pm2) Excellent. But now I am a bit confused, why is it that most people try to mimimize pipe distances from reactor to heat exchangers?
3) Again good. And again confused, if the setup is equally efficient from 500-1000, why are people so focused on heating things up to 999 degrees?
A heat exchanger will start working at 500°C using up a set amount of heat. For it to keep working that heat has to be replaced from the heat pipe, meaning the heat pipe has to be x°C hotter to allow enough flow into the heat exchanger. Same between each pair of heat pipes. So the maximum distance a single heat exchanger can be from the reactor is 500/x m.
But usually you have more heat exchangers. So where the second heat exchanger pulls it's energy the temperature difference has to be 2x. With 3 heat exchangers it has to be 3x. For 16 heat exchangers the first must be within 500/x/16 m from the reactor, which isn't very far. You can calculate it exactly from the game values or experiment with placing heat exchangers at different distances. What you will see is that the heat pipes will be at a lower temperature the further away from the reactor they are even with the reactor at 1000°. At some point the heat exchangers will stop working 100% because the heat difference simply won't allow enough heat to flow. The temperature will be below 500+x°C. Think of it as a river. The steeper the gradient the faster the water flows and you need a certain throughput.
Also: On fuel insertion a heat exchanger closer to the reactor starts working faster. That means the steam reserve doesn't have to be so big.
