Description

"The advanced furnace comes with integrated inlet and outlet pumps for controlling the unit's internal pressure." — Stationpedia

The Advanced Furnace is used to create advanced alloys, but can be used to create basic alloys as well. It lends itself to automation. The Maximum pressure for the furnace is 60 MPa before the furnace will, in short order, explode. Adding Hydrocarbons, i.e. coal, will increase the pressure. Contains two embedded volume pumps to control flow in and out, in order to use them, the furnace must be powered, and setting both to zero will put the furnace in a state of quiescence, but the furnace will slowly lose pressure and temperature. The capacity of the furnace is in excess of 5kg of materials so it is possible to make a full 500g ingot of an advanced alloy in one go.

In the early game, a regular Furnace will be easier to make and operate.

Usage

While it is possible to operate the advanced furnace similar to a regular furnace (add fuel, ignite, add ore), the most common setups for advanced furnaces are:

  • ice only smelting
  • fuel mixing
  • hot and cold mixing

Ice only smelting

In this setup ice is fed into the input slot of the furnace prior to loading ores for smelting.

Note that at least one gas pipe must be connected to both the input and output gas lines to avoid error conditions.

+++ For Inconel the mixture pressure will overshoot the range slightly, either make the alloy when the pressure rises into the range, or a short wait will be necessary in order for the pressure to drop back into range.

^^^ The excess Oxites are necessary in order to limit the temperature of the mixture, however they can be substituted with other inert gasses.

Gaseous Fueling

ice crushing

  • ice crushing*, gas collection and measuring setup''']] In this setup fuel is pumped into the furnace from either pre-measured canisters or pumped into the furnace in measured amounts. Fuel can be either a 2
    Volatile to O₂ mixture, raw gases from Volatile and Oxite ices, or Superfuel. Raw gases can be collected by putting Volatile Ice and Oxites into an Ice crusher, or by melting the gases in an enclosed area and pumping the gases into a canister with an active vent. Superfuel can be made by collecting N₂O and mixing it with Volatiles at a 1
    Ratio. Raw gasses made from ices will have a ratio of 3.6% Nitrogen, 32.7% Oxygen, and 63.7% Volatiles, and the Volatile to Oxygen ratio will be 1.95
    instead of 2
    , but it will burn adequately well.

Do not degas the ores, Stellite, Hastelloy and Waspaloy all rely on the nitrous oxide produced from the silver ore and lead ore used in their production. Do not substitute an ingot for an ore. Feed the ores into the furnace in the listed order. Use the listed amount of ores, using less ore or more ore will result in an different pressure and temperature.

^^^ These recipes use CO₂ @ 0°C as a pressurant. Other pressurants such as Nitrogen, Pollutants, and Oxygen are possible, but they may result in different outcomes.

Fuel mixing

rudimentary setup for mixing H₂, O₂, and dilutant

  • rudimentary setup for mixing H₂, O₂, and dilutant* In this setup, the furnace's input is connected to a gas mixer to provide fuel, and often a dilutant (used to increase the pressure without spending extra fuel). The Furnace temperature and pressure math article contains formulas useful for crafting recipes to hit temperature and pressure targets.

Hot and cold mixing

This setup involves a hot tank and a cold tank of gasses, which are then mixed to achieve a target temperature and pumped in to achieve the target pressure. On most worlds maintaining a cold tank is quite easy (because the atmosphere on most worlds is below the temperature needed to smelt ore). Maintaining a hot tank is a little trickier, and either involves a lot of energy spent on Pipe Heaters, or an auxiliary furnace to combust fuel and pipe the exhaust into an insulated tank. Another easier option is to have the entire setup, furnace, pipes and tanks, in an enclosed vacuum chamber, so heat remains in the gases. Note that the outside atmosphere on worlds with no air doesn't count, it must be an enclosed chamber with all air pumped out
