Fuel Processor

A 3x3 machine that turns any fuel into Processed fuel without losing energy, plus a built-in +10% productivity bonus.

Features

Energy-conserving: each fuel becomes processed fuel worth the same total fuel value. For example, 1 solid fuel becomes 3 processed fuel, and 2 wood become 1. High-value fuels like rocket fuel turn into a whole pile.
+10% productivity on top, built into the machine.
Free to run: needs no power, no fuel, and produces no pollution.
Furnace-style: just insert fuel and it picks the recipe automatically.
No modules, no beacons: it has no module slots and ignores beacons.
Processed fuel works exactly like coal (same fuel value, stack size and fuel category), but is white so it's easy to tell apart on belts.
Works with modded fuels: recipes are generated at load time for every burnable fuel, including fuels added by other mods.
Processed fuel can't be fed back in, so there's no recursion.

Speed

Processes 4 MW of fuel: 4 MJ of input per second, the equivalent of one coal per second. With the +10% productivity, 4.4 MW of processed fuel comes out.
The rate is the same for every fuel. Low-value fuels go through quickly in item terms, and high-value fuels like rocket fuel take a long time per item.

Unlocking

Research Fuel processing, which requires Advanced material processing and costs 100 × red + green science.

Building recipe: 10 steel plate, 10 stone brick, 10 iron gear wheel, 5 pipe, 5 electronic circuit.

Settings

Accept all fuel types (startup, off by default): also accepts non-chemical fuels such as uranium fuel cells and Gleba nutrients. When off, it only takes fuels a furnace could burn.

Compatibility

Factorio 2.0 and 2.1 (separate releases; the game picks the right one).
Works with or without Space Age.
Uses its own prefixed names, so it won't conflict with AAI Industry or other fuel-processing mods.
