Sandustry Slag Burner: Current Residue Burner Layout
Quick answer
Explains the current Residue burn-zone setup behind older Slag Burner searches.
Quick Answer
There is no separate official machine named Slag Burner in the current Sandustry entity list. Players usually mean a controlled burn zone for Residue, the Shaker byproduct that older guides often called Slag. Burn Residue to create Burnt Residue, then drop Burnt Residue through a Kinetic Press from at least 25 blocks to produce Gold and Seed.
For the material chain, see the Slag terminology page and Burnt Residue guide.
Current Burner Setup
| Part | Purpose | Current note |
|---|---|---|
| Residue input | Feeds the burn zone | Comes from Wet Sand processed by Shakers |
| Ignition source | Starts conversion | Flamethrower, Fire, Lava, Rocket Launcher napalm, or Pyro Dispenser |
| Containment | Stops leaks and mixed output | Keep Water, Gold, and Seeds out of the burn area |
| Burnt Residue filter | Separates usable output | Route only Burnt Residue toward the press tower |
| Return lane | Handles unconverted Residue | Burning is probabilistic, so some input must loop or be stored |
The key difference from older guides is the output: the current chain does not create Spores from the press. It creates Seeds.
Lava-in-Filter Burner
The official Lava page documents a useful automation pattern: Lava trapped inside Filters can ignite passing Residue. That makes a compact burner possible, but it still needs containment. Treat the burner as a hot maintenance area, not as a normal conveyor intersection.
Recommended checks:
- Keep the Residue stream shallow before it reaches the heat source.
- Give unconverted Residue a return path or storage bin.
- Do not let Water touch the burn zone unless you deliberately want Steam.
- Put the Kinetic Press tower after filtering, not directly under a messy burn pile.
Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Residue passes through unchanged | Not enough contact with ignition | Slow the stream or widen the hot area |
| Burnt Residue output is lower than expected | Conversion is chance-based | Plan for losses instead of assuming 1:1 output |
| Press clogs after the burner | Mixed input reached the tower | Add a Burnt Residue-only gate before the drop |
| Fire damages nearby factory parts | Burn zone is too close to logistics | Move the burner into a contained side module |
