Coal Generator

The Coal Generator is a power generator building that generates power by burning , or and . It is the first fully automated power source the pioneer has access to and also the first source to use a mined resource.
One Coal Generator produces 75 MW at 100% clock speed.
== Fuel consumption ==
At 100% clock speed, one Coal Generator consumes 45 m Water/min, no matter what fuel is used.
This means 3 Water Extractors will produce enough water for 8 Coal Generators, provided the 300 throughput limit of the Mk.1 Pipeline isn't exceeded (see below for a layout of possible setups which don't exceed the Pipeline limit).
Fuel type	Energy (MJ)	Stack size	Stack energy (MJ)	Burn time (sec)	Items per minute
 	300 	100 	30,000 	4 	15
 	630 	100 	63,000 	8.4 	7.142857
 	180 	200 	36,000 	2.4 	25
== Generators per Coal node ==
Use the following equations:
Number of Coal Generators required:
Coal generator = Coal mining rate / 15
Number of Water Extractors required:
Water extractor = Coal generator / 2.6666
Spread out the water supply across multiple pipelines as following:
Pipelines required = Coal generator / 6.6666
* Coal burn time is four seconds, which means that a single Coal Generator consumes 15 Coal/min.
*Pipelines Mk.1 only have a capacity of 300 . Thus, when connecting Water Extractors to a line feeding seven or more Coal Generators, Water inputs either need to be spaced out or be separated.
** Alternatively, underclock Water Extractors to 75% and connect each of them to exactly two Coal Generators. That way, the number of Water Extractors is half the number of Coal Generators.
** Using Water Extractors underclocked to 75% require an additional extractor for every eight Coal Generators, trading space for ratio simplicity. For eight Coal Generators you either need three Water Extractors at 100% (3 * 20 = 60 MW) or four Water Extractors at 75% (4 * 12.6 = 50.4 MW). This can be useful early on when you still need to save up on energy consumption on Water Extractors.
** A Water Extractor has about the same width as two Coal Generators so it would be easier to tile the layout.
*Pipelines Mk.2 have a capacity of 600 . Thus up to 13 Coal generators and 5 Water Extractors can be connected to a single Mk.2 Pipeline.
* A Miner Mk.3 on a pure Coal node should only be overclocked to 163%, due to the throughput limit of Mk.5 conveyors.
* As the Miner and Water Extractors consume power, the net power capacity is less.
** Water Extractors use about 10% of the gross Power generated. After subtracting 10% from the gross Power, subtract the Power consumption from the Miners, Pipeline Pumps, vehicles, etc. to calculate the net power produced.

== Generators fueled by Compacted Coal ==
This is a simplified version of the table above that do the same calculations for as input, so only 7.143 items per minute instead of 15 are needed.
Each Assembler operates at 25 parts per minute.

== Generators fueled by Petroleum Coke ==
Burning for power can be a great way to deal with Heavy Oil Residue, as long as overflow is handled (to prevent the Coke from backing up, which would result Heavy Oil Residue backing up and subsequently Plastic or Rubber production stopping). One Coal Generator consumes 25 Coke per minute.
As the amount of Heavy Oil residue can vary significantly based on what recipes are used, the table below only calculates with Heavy Oil Residue and not Crude Oil.

=== Compact Placement ===
Coal Generators can be hard to align when built in two opposing rows fed by a central belt and pipe, due to their large size. However when built right to left, they can be squeezed, down to 8 meters (a foundation width) center-to-center. Make sure not to use the 'snap' mode, only use manual align.

== History ==
* Patch 0.3.8.2: Fixed Fluid indicator UI not displaying properly in the Coal Generator
* Patch 0.3: Now requires Water to operate, appearance changed accordingly to include a Pipeline input. The chimney is now fully within the hitbox.
