Description

Kayser's Smelting Furnaces

The Compactest Smelting Furnaces

Current as of: U3 (v0.7.4)

  • Furnaces for: Iron, Copper, Steel, Glass, and Silicon. (Aluminium and Titanium might be added later)
  • Purpose: Early/Mid-game start-up and incremental development (speedrunning)
  • Ultra-compact, cheap to construct and operate. Low construction cost to get started.
  • Blast Furnaces (T1/T2) and Arc Furnace II (T4) versions. T3 where feasible (Silicon).
  • Upgrades from Blast Furnace I to Blast Furnace II without any demolishing.
  • Upgrades from Blast Furnace II to Arc Furnace II with minimal demolish (input manifold).
  • Interconnected exhausts (and low steam) for easy connection to exhaust filtration and steam recovery.
  • UPDATED: Comes with useful storage arrays for easy mapping of transports, trucking, and/or alerts.
  • UPDATED: New tiling concept where the BP is extended by tiling onto itself with some overlap. No useless belts or pipes hanging as with normal tiling blueprints. (See image 7)

General Usage:

  • Plyg & Play ready, just deploy and go up to rated capacity. In some cases, belts and pipes may require an upgrade to reach full capacity.
  • To extend further, paste blueprint overlapping itself (two furnaces of the BP sticking out, furnaces aligned and tight against each other). Upgrade old belts and pipes as required to meet new capacity.
  • Note: Ore crushers, hydrogen production, and graphite production are not included in the blueprints.

Iron, Copper, Steel:

  • To upgrade from Blast Furnace I to Blast Furance II, replace the ore input with crushed ore input. Place T2 blueprint. Start feeding the secondary ingredient (limestone/sand). Wait until all the regular ore is fully consumed before upgrading the actual furnace.
  • To upgrade from Blast Furnace II to Arc Furnace II, demolish the coal belt, coal storage, and the jiggly limestone/sand belts to the furnace inputs. Then align and place the T4 blueprint on top of the existing furnace. New input manifold should be constructed, including water and graphite, and the low steam output should fit on the back.
  • UPDATED: Steel now includes Oxygen production.

Other:

  • BPs generally include smokestacks for Exhaust (and Low steam for T4). As Exhaust Filtration becomes available, it is recommended to replace the smoke stacks for Exhaust (and Low steam) with Exhaust scrubber (Thermal desalinators or Water tower for Low steam).
  • Some BP have permanent red disconnect icons caused by adjescent connectors. This will not disrupt operation.
  • Most blueprints share similar connection signatures: on the input side, main ingredient is on tier 0, tier +1 is coal, tier +2 is the secondary ingredient and tier +3 is graphite, +4 is water.
  • Inputs always run in one direction and outputs in the opposite direction.

Enjoy your smelting!

BROOOOO you can make blueprints now that allow the BP to auto place a lower tier of module if the upper tier isn't researched? CoI devs are being a li'l SPICY. Also, well done to you as well. TIGHT plan.
I may be wrong, but I think a single molten channel doesn't have enough throughput for 8x silicon reactor so ARC II silicon BP won't be able to run at 100% speed ? but maybe u can fix it by using molten balancer like I did here btw https://hub.coigame.com/Blueprint/Detail/672
@NEET ENGINEER Thank you for this wonderful comment. Issue fixed.

There is only one logistics problem with smaller storages — vehicles don’t handle them well in the new update.
@YuS, can you elaborate?

@Kayser When high-volume resource demand comes from production, small storages cannot meet the demand. I managed to solve this by connecting a large storage to the small one via a conveyor. Obviously, delivery distance also matters.
Storages included are intended to get you started with truck deliveries, but then connected to transports ASAP and then only used as small buffers and allow you to set alerts to monitor for issues.
