Industrial Coke Oven

The Industrial Coke Oven (ICO) is an EV tier multiblock for mass burning logs into charcoal and one fluid byproduct (coal gas, wood gas, wood vinegar, wood tar, or charcoal byproducts). The fluid byproducts are useful for producing organic compounds such as ethylene, benzene, and toluene. The ICO is a direct upgrade from the Pyrolyse Oven and Advanced Coke Oven because it gains a 2% energy discount per heating coil tier (multiplicative) and offers 32 parallels plus 16 per additional slice added to the structure. The number of slices is capped at 16 for all heating coil tiers except eternal which has no limit. The ICO also unlocks the ability to use one multi-amp energy hatch with infinity heating coils or better.

The ICO has two tiered components. The coke oven casings determine both the base number of parallels and the additional number of parallels per slice. The heating coils determine the energy discount of the machine. Buses/hatches may replace any structural coke oven casing on the base structure--NOT the additional slices. Laser energy hatches are not supported, but there can be multiple regular energy hatches for overclocking or one multi-amp energy hatch if the heating coils are infinity or better. Use the Multiblock Structure Hologram Projector to visualize/build the structure with subchannels "coke_oven_casing" and "coil" to specify the tier of those components and subchannel "length" to specify the total number of slices.

Wallsharing

ICOs may wallshare nearly their entire structure with another one on the opposite end and flipped horizontally. This is highly recommended because it saves an incredible amount of casings, frame boxes, and heating coils--the second machine is basically free. However, buses/hatches are limited to the base structure and therefore cannot be shared in that configuration. No recipe uses more than 1A of power regardless of the energy discount so it is possible to share one energy hatch between two machines.

The ICO is a direct upgrade from the Pyrolyse Oven and Advanced Coke Oven because it gains a 2% energy discount per heating coil tier (multiplicative) and offers 32 parallels plus 16 per additional slice added to the structure, as seen in the following tables. The number of slices is capped at 16 for all heating coil tiers except eternal which has no limit.

The ICO is primarily used to burn logs into charcoal with the option of ONE fluid byproduct--determined by the programmed circuit in the input bus or controller. The most common choice is charcoal byproducts because it breaks down into dimethylbenzene, wood gas, wood vinegar, and wood tar in a Distillation Tower. Another common choice is wood tar for making nitrobenzene more directly/efficiently. There is also the option to use 250L of nitrogen gas per 4 logs to double the processing speed of the machine, which is again determined by the programmed circuit in the input bus or controller. The following is a non-exhaustive list of the available recipes with their programmed circuit in brackets.

• [1] Creosote Oil
• [2] Creosote Oil (requires nitrogen)
• [3] Charcoal Byproducts
• [4] Charcoal Byproducts (requires nitrogen)
• [5] Wood Gas
• [6] Wood Gas (requires nitrogen)
• [7] Wood Vinegar
• [8] Wood Vinegar (requires nitrogen)
• [9] Wood Tar
• [10] Wood Tar (requires nitrogen)
• [11] Heavy Oil
• [20] Coal Gas (requires steam)

There are other ICO recipes such as turning bio chaff into fermented biomass and coal into coal coke which may be useful depending on your available resources and goals. The machine is highly versatile and serves a variety of purposes beyond producing charcoal.

The Pyrolyse Oven is another option for producing radox and seemingly the wrong choice after upgrading in EV. However, the ICO only outperforms the Pyrolyse Oven when it can take full advantage of its parallels. To help decide between a full-length ICO and the Pyrolyse Oven, the following table compares the average L/s of radox for various heating coils and overclocks. The cells highlighted green mean the Pyrolyse Oven is faster than the ICO and the cells highlighted red mean the Pyrolyse Oven is slower.

From this information, it can be concluded that the Pyrolyse Oven is the superior option for 0-1 overclocks and the ICO is the superior option for either 2+ or 3+ overclocks depending on the heating coils.
