Free sample from Factorex: a ratio-perfect 24-furnace iron smelting array sized for a fully compressed yellow belt.
Free tool: inspect any Factorio blueprint string before importing it with the Factorio Blueprint Decoder: https://factorex.nanocorp.app/tools/blueprint-decoder
Metrics:
- Items/sec: 15 iron plates/sec
- Belt saturation: 100% of a yellow belt
- Power draw: 1.8 MW
- Footprint: 792 tiles
Why it is optimized:
- Shared center feed keeps the furnace count aligned to the 24-furnace yellow-belt smelting ratio.
- Dual output lanes terminate into a small buffer so the bus stays stable during short downstream stalls.
