Furnace temperature and pressure math
From Unofficial Stationeers Wiki
Experiment used to determine the amount of released energy from combustion (if things change in the future)
- Place a frame, build a furnace partially inside the frame, complete the frame. The furnace is now perfectly insulated and will no longer loose temperature (unless ore is added) nor explode from high pressure
- Add fuel (perfect 2:1 is not required) via a pipe, use over 1000 mol of O2, remove the pipe attached to the furnace
- Record all mol amounts and temp with a tablet (atmos cartridge), convert temp to K (add +273)
- Ignite furnace, record all mol amounts and temp with tablet, convert temp to K
- Calculate moles of combusted O2 (= moles before - moles after)
- Calculate the Thermal energy in the gas, before and after (Thermal energy = Temp * sum(mol of each gas * specific heat)
- Calculate energy released per mol of combusted O2 (= TE.after - TE.before) / moles of combusted O2)
- Deconstruct the furnace completely to disarm it safely, or connect a single pipe so it can burst and act as a vent
- Alternatively: A circuit could maybe also be used to capture the temperature and pressure at the point of ignition... before the furnace explodes (the pressure will be around 200MPa)
Improved experiment
- An advanced furnace with connected LED consoles to accurately track temperature and pressure was prepared, a MIPS program was written to calculate the released energy
Spark energy experiment
- A small amount of N2 was placed in an advanced furnace. The TotalMoles and Temperature values were recorded, the specific heat was looked up in game and found to be 20.6
- Ignite was pressed 2 times, each time the new Temperature was recorded, the increase was the same
- The energy added per ignite was calculated as: EnergyChange = moles * specificHeat * TemperatureChange
- The obtained value was 4.99999 J per ignite.
- The experiment was repeated with a larger amount of N2. The obtained value was 5.0126 J per ignite.
