For doing stellite manually it’s very helpful to not keep turning the fuel input and pressure relief off and back on. You have to find a balance point where pressure isn’t building too much but fuel continues to flow in to keep the temperature rising. This requires having both its input and output pumps (they’re not valves btw) going at the same time. Definitely doesn’t require NOS as you showed! But is tricky.

Managing the furnace becomes much easier once you encapsulate the furnace in a small room(use walls, not a frame). This helps the furnace retain it's heat(above 100kpa inside the room) since it tries to heat up the air around it to balance it out- but because it's in a small room, there's less air to heat up. But you'd need to be careful with the pressure on the inside, as the air heats up it'll expand and increase the pressure (recommended to use stellite glass + composite windows). Using the fact that the fact that the furnace deletes heat when the air around it is less than 100kpa- you can set up a cooling/heat system. Increase the room pressure past 100kpa, and add fuel to increase temperature- let waste gas out if pressure is too high. Decrease room pressure below 100kpa and add fuel to increase pressure while lowering the heat.

If you just inject H2 and O2 in a 2:1 ratio, and ignite it then it'll burn at a constant 2200 degrees (can't remember if that's K or C but it doesn't matter). The point is that after you melted the initial 3 ores, the gases in the furnace are too cold, so just exhaust those out into your overflow tank, until your furnace is empty and then inject some more fuel and ignite it. That'll get you up to temperature right away, and then you just keep adding a bit of fuel and igniting to get the pressure you want. It'll slowly lose temperature because the furnace isn't insulated, but it won't be that fast. Otherwise, a good informative video. Thanks!

The advanced furnace has built in pumps for exactly that reason, so you CAN pump gas in even if the furnace is at some ungodly high pressure and your fuel mix is really low pressure.

Im a bit late to this comment thread.. but i see alot of people in various boards struggling with stellite and the answer is NOS fuel. 1:1 nitrous oxide to volatiles. It burns much hotter than the alternative. Cheers.

Most important takeaway for me as an AF noob: Pressure. So, I put a big inline tank after a turbo volume pump, got it to 45 MPa quickly, and now I can furnace away! :D

I wish I had had this video when I was figuring out how to use the advanced furnace! All the videos I could find were some absurdly complex system of IC or a maze of logic chips. Put me off of the advanced furnace for a looooong time before I realized you don't actually need that. Still, even for a first timer this -is- the advanced furnace. Maybe it would have been worth talking about insulating the furnace and including a cold gas line?

You don't need to pressurize the fuel intake. The controls on the Furnace are volume pumps not valves.

Sub for sure

Ist the way to Start. You need to know how to operate a System by Hand before you can automate it.

Yeah, with this build it works - but is extremely unefficient - because its heating its enviroment - and wasting the fuel.

Doesn’t the furnace increase the temp of the room now?

Where is the setup?????

What game is this?
