The oxygen
does make a difference in the heat, at least it used to and I can't imagine why that would change. In my experience with the machine, adding oxygen accelerant to the PJF caused its temperature to increase faster than even multiple cooling fins could dissipate, even with fans attached, which only slowed the temperature gain marginally. I don't recall oxygen increasing the temperature significantly while water was also being used; it still wouldn't smelt HSLA, which meant finding a way of running the machine dry if I wanted it to make steel, regardless of whether or not I was adding accelerants. If it does, what temperature does it stabilize at and are you getting the full speed benefit from the oxygen? The reason I ask is because the PJF devours oxygen tanks, certainly
much faster than I was producing it.
I was also certain that oxygen acted an HSLA multiplier. /shrug
I don't see anything in the change logs that would indicate that any of this was changed in the past year.
Here's the solution I came up with last year:
The cooling fins and fans are optional but extend the duration of each duty cycle and cool the PJF a little faster while it's shut down. It's completely automated and completely safe --- er, that is barring using it on a live server that is experiencing a lot of bad TPS spikes (oops!) ... I actually still need to make some adjustments to this arrangement, lol
[Edit] Digging this up has jogged my memory somewhat, I think. Let me see if I've got this right:
Adding water as coolant to the PJF stabilizes the the operating temperature close to but less than 900C. Since smelting raw iron into HSLA steel requires temperatures above 900C, the PJF must be operated without water. Cooling fins can stabilize the temperature above 900C, iirc, somewhere in the range of 950C(?). Adding oxygen accelerant causes the PJF to very quickly overheat, even with cooling fins, and explode at 1000C in exchange for greatly increased HSLA production speed (and possibly a chance of ingot doubling per operation?).
