Volcanus

The Volcanus is an IV tier multiblock for smelting dusts into ingots, crafting silicon boules, and heating up various materials. The Volcanus is a direct upgrade from the Electric Blast Furnace because it runs at 220% speed, only uses 90% of the EU/t normally required, and offers a fixed 8 parallels. During operation, it consumes 10 L/s of blazing pyrotheum through a specialized pyrotheum heating vent. If it ever runs out, the machine crashes immediately and causes a random maintenance issue to occur. The Exothermic Hearth only outperforms the Volcanus if it can take full advantage of its 512 parallels (4+ overclocks).

The Volcanus has one tiered component. The heating coils determine the maximum tier of recipes and the number of perfect overclocks. Buses/hatches may replace any casing anywhere on the structure. Multi-amp and laser energy hatches are not supported, but there can be multiple regular energy hatches for overclocking. Use the Multiblock Structure Hologram Projector to visualize/build the structure with subchannel "coil" to specify the tier of the heating coils.

Structure

• Controller: Front bottom center
• 16 Heating Coil (Tiered)
• 6-13 Volcanus Casing
• 1 Pyrotheum Heating Vent: Any casing
• 1+ Energy Hatch: Any casing
• 1 Maintenance Hatch: Any casing
• 1 Muffler Hatch: Any casing
• 1+ Input Bus/Hatch: Any casing
• 1+ Output Bus/Hatch: Any casing
• Mandatory Air: Interior of the structure

Wallsharing

Volcani may wallshare each of their sides to save on casings and buses/hatches. No recipe uses more than 1A of power so it is possible to share one energy hatch between two machines.

The Volcanus is a direct upgrade from the Electric Blast Furnace because it runs at 220% speed, only uses 90% of the EU/t normally required, and offers a fixed 8 parallels. It also has no restrictions on the location of buses/hatches which makes it much easier to build and wallshare.

The heat efficiency bonus for using higher tier coils still applies. Every 900K over the minimum heat capacity of a recipe reduces the EU/t by 5% (multiplicative). Every 1,800K over the minimum heat capacity of a recipe grants a perfect overclock. The only difference is that the Volcanus does NOT gain +100K for every voltage tier above MV.

Furthermore, the Volcanus consumes 10 L/s of blazing pyrotheum during operation through a specialized pyrotheum heating vent. If it ever runs out, the machine crashes immediately and causes a random maintenance issue to occur. Pyrotheum is primarily sourced from blazes or the pyrotheum bee. Alternatively, centrifuge netherrack dust (from nether stonelillies) to produce three out of the four dusts needed in the mixer recipe.

The difference between the Volcanus and the Exothermic Hearth (ExH) is not entirely obvious. The former has a very generous speed bonus but the latter has significantly more parallels. To help decide between the two, the following table compares the processing speed of raw neutronium dust with nitrogen gas for various overclocks. The ExH values are calculated with the maximum 512 parallels so its performance could be slightly worse in practice. The cells highlighted green indicate which multiblock is faster after normalizing for power.

From this information, it can be concluded that the Volcanus is the superior option for 0-3 overclocks and the ExH is the superior option for 4+ overclocks. This behavior is consistent across all recipes and heating coil tiers.
