ColonelThirtyTwo: Add note about the temperature at which temperature steam exchangers start making steam.

{{Languages}}
{{Stub}}
{{:Heat exchanger/infobox}}

The '''heat exchanger''' exchanges heat between a heat source and a fluid. It is usually used together with a [[nuclear reactor]] and [[steam turbine]]s.

Heat Exchangers will not produce steam until they reach 500°C.

Offshore pump

2017-01-21T00:47:57Z

ColonelThirtyTwo: Rewrote description. Explain the basic functionality (placement, etc) before its use in steam engines, and also mention that it doesn't affect the body of water it's connected to.

{{Languages}}
{{:Offshore pump/infobox}}
The '''Offshore Pump''' produces [[Water]] from a lake or ocean. It must be placed on a shoreline of a body of water on the map, and connected to a [[Liquids system|pipe or other object that accepts liquids]] (it does not require [[electricity]] or [[fuel]]). It produces 60 units of water per second.

Offshore Pumps are frequently used to provide water for [[Steam engine]]s, though several crafting recipes also require water. One offshore pump can generate enough water for 10 steam engines (see the [[Power_production#Steam power optimal ratios|optimal ratios]] for power production).

The water supply from an offshore pump is endless; it will not dry up the body of water it is attached to (to do that, use [[Landfill]]s). Additionally, the size of the body of water the pump is connected to does not affect the rate of water generation.

Burner mining drill

2017-01-21T00:08:53Z

ColonelThirtyTwo: Rewrote the description to flow a bit better.

{{Languages}}
{{:Burner mining drill/infobox}}

The '''Burner Mining Drill''' is the first type of drill accessible to the player. It burns [[fuel]] to [[Mining|mine]] the ore underneath the 2x2 area it is placed on.

It mines about 7 items per single unit of coal used to fuel it, producing 0.28 items/s for [[Copper ore]], [[Coal]] or [[Iron ore]] and .3675 items/s for [[Stone]]. Burner miners create a lot of [[pollution]] per item.

Burner drills are usually used until the player has built an [[Electric system|electrical network]], at which point the larger and faster [[Electric Mining Drill]] becomes more useful.

# Amount of [[Fuel]] in the Mining Drill
# Depletion of 1 Unit of [[Fuel]]
# Progress of Mining
# Product
==Self-Sustaining Coal Mines==
Both methods require no electricity.
=== Method 1 ===
Two burner mining drills can refuel each other when placed next to each other on a coal deposit as long as they're facing each other. Each drill fuels the other and coal gradually accumulates in their [[Storage/Stack]]s, so you have effectively a storage of 100 coal (2 stack, 50 coal, one in each burner miner, together 100). You can do this also for 4 or any other even number of miners.

[[File:Early_coal_mining_1.jpg‎|upright=2]]

=== Method 2 ===
This method can be used for any number of burner mining drills in a coal deposit. Place a burner mining drill, then place at least three [[Transport belt]]s from the output in a mirrored "L" like shape so that the third belt has a gap between it and the miner. Fill the gap with a [[Burner inserter]] in a way that the inserter can insert coal to the miner.

Oil refinery

2017-01-20T23:43:55Z

ColonelThirtyTwo: Fixed a grammar mistake in the first sentence.

{{Languages}}
{{:Oil refinery/infobox}}

The '''Oil Refinery''' processes [[Crude Oil]] into 3 different fluids: [[Heavy Oil]], [[Light Oil]] and [[Petroleum Gas]].

Oil products have many uses. Although they can be turned into [[Solid fuel]] to fuel [[Boiler|boilers]] and furnaces, it is usually used to create [[Plastic]], which is used in [[Advanced Circuit|Advanced Circuits]], and [[Sulfur]], which is used in more advanced items. They are also used as ammunition for [[Flamethrower|flamethrowers]] and [[Flamethrower turret|flamethrower turrets]].

== Recipes ==

The refinery has two available recipes, one of which must be set before it can begin processing.

Steam engine

2017-01-19T20:28:59Z

ColonelThirtyTwo: Expand on the description.

{{Languages}}
{{:Steam engine/infobox}}

'''Steam engines''' are the most basic [[Electric system|electricity]] generator, available to the player at the start of the game. They produce [[electricity]] by consuming hot [[water]], pumped from an [[offshore pump]] and heated with [[Boiler|boilers]]. Higher temperature water (up to 100 C) yields more electricity.

Steam engines will automatically adjust their power production and water usage based on the current demands of the electricity network. Hovering the mouse over a steam engine will display their current power production ('''Performance''') and their possible power production with the fluid they have ('''Available Performance''').

Steam engines have two ports, allowing excess water to flow through. This allows steam engines to be chained together. The current optimal ratio is 1 [[offshore pump]] to 14 [[boiler]]s to 10 [[steam engine]]s to 2.5 coal [[electric mining drill]]s.

Steam engines themselves do not produce [[pollution]], however, the [[Boiler|boilers]] used to heat up the water do.

== Using other liquids ==

The steam engine can use any type of liquid to generate electricity. This can be used to get rid of unused oil-products. Just fill unusable oil products into a steam engine and it will destroy the liquids (cold liquids will be destroyed at a rate of [https://forums.factorio.com/viewtopic.php?p=144748#p144748 6.0 fluid / second]). It works the same as for cold water; you don't need to warm it. If you heat the liquid before that, the hot oil will produce electrical power, just like with hot water.

By default, water is 15°C and oils are 25°C. The steam engine happens to work with water from 15°C and oils from above 25°C (a complete coincidence). An oil temperature of 25.22°C will get you about 1.3KW of power. Heating up water or oils makes no difference: heating one liter of water from 15 to 16 degrees takes just as much energy as heating one liter of oil from 25 to 26 degrees[http://because.a.tweet.doesnt.fit.lucb1e.com/?text=1.4k+water+15%B0C-%3E17.73%B0C+and+1.4k+light+oil+25%B0C-%3E27.82%B0C%2C+both+using+1+coal+in+a+boiler%2C+filling+an+empty+tank+from+a+full+tank+until+the+coal+boiler+runs+out.+I+stopped+a+bit+early+on+the+water+one+and+the+difference+seems+negligible. (OC)]. It was not tested how much energy the steam engine produces with 16°C water versus 26°C oil, but it probably does not warrant using oils instead of water.

In general you should convert the unusable oil products into useables, instead of just making electricity out of it!

Electric furnace

ColonelThirtyTwo: Rewrote the description to describe the furnace and advantages better.

{{Languages}}
{{:Electric furnace/infobox}}

'''Electric furnaces''' are the third and last tier of furnaces. As their name implies, they use [[electricity]] rather than [[fuel]] to operate, removing the need for a fuel belt.

Electric furnaces smelt items at the same speed as a [[Steel Furnace]], and also have two slots for [[Module|modules]]. However, they are slightly larger than the other two tiers of furnaces; they occupy a 3x3 area instead of a 2x2 area.

As electric furnaces consume a substantial amount of power, [[Module#Efficiency Module|Efficiency modules]] are a good option.

Accumulator

2017-01-19T18:46:44Z

ColonelThirtyTwo: Add info on how to use with a circuit network.

{{Languages}}
{{:Accumulator/infobox}}

The [[Basic accumulator]] stores a limited amount of energy when available production exceeds demand, and releases it in the opposite case. The basic accumulator stores up to 5 MJ of energy. Charge/Discharge rate is 300 kW maximum.

== Notes ==
* 5MJ of stored energy take approximately 17s to fully charge/discharge at the maximum rate of 300kW. Read [[Game-second]] for further time related calculations.
* When discharged above maximum speed by multiple unconnected poles, will distribute energy unequally (some may get 100% demand, others 0%)
* May be used to provide limited amount of power (multiples of maximum charge rate) to a section of the grid
* Produces light when charging and discharging
* Can act as a emergency backup for your base in case of blackout, until main power supply is restored
* Can be used to power the base at night if it relies heavily on [[solar panel]]s
* Can act as a "surge protector" (if power usage of one device exceeds production for a few seconds or so, the basic accumulator will compensate for this and provide power to the grid until said device shuts down or requires a lesser power requirement)

== Circuit Network ==

If connected to a [[circuit network]], an accumulator will output its level of charge, as an integer from 0 to 100, to a specified signal.

== Other uses ==

=== Isolation of Power Networks ===

[[Electric network#Storage|Accumulator]]s can be used to isolate two separate power networks, which has a number of uses. Since accumulators have a lower delivery priority than any other entity, this guarantees that they only receive energy when you have enough left over after powering all other entities in a network. At the same time, accumulators can also be used to deliver energy in another electrical network, and can charge and discharge at the same time. Consider the following example:

[[File:Accumulator_Network_Isolation.png]]

The two power networks A and B are not directly connected to each other: They are connected only through the accumulators, which are shared by both networks. This is accomplished by setting up electric poles for each network connected to the accumulators, then ensuring the sets of poles are not connected to each other (which can be done by crafting a copper wire then dragging it between two connected poles to sever the connection, exactly as is done for disconnecting circuit wires).

In the above example:

* The accumulators will only charge if extra power is being produced by network A or B.
* The accumulators will discharge as needed into either network if one is not producing enough power.
* Since the maximum input/output rate of an accumulator is 300 kW, power flow between the two networks will be limited to 300 kW times the number of accumulators (1.5 MW in the example).
* Note that this isolation is bidirectional: Either network can charge the accumulators, and the accumulators can discharge into either network.

This technique can be used whenever this type of isolation is desired.

==== Reduce Energy Consumption in Critical Situations ====

In particular, one good use for the above technique is to limit electricity consumption in low power situations by isolating non-critical parts of your factory (such as [[Radar]], [[Lab]]s, [[Electric furnace]]s, [[Electric mining drill|electric miner]]s, [[Beacon]]s, etc.) from critical parts (such as lasers, ammo production, or whatever your priorities are).

To do this, place your main generators and critical components on one network and place your non-critical components on another network, isolating the two as above. Now, two things will happen:

* Power will ''only'' flow to the non-critical network when you are generating a surplus on the main network, and
* The rate will always be limited to 300 kW per accumulator.

Because the accumulators will only receive power if you have a surplus on the main network, this will in effect deactivate the low-priority network when electricity is in short supply. This will also limit power consumption by the low priority network if its usage becomes high, for example if you have two factories on a low priority network and usually only one of them runs at a time, if both happen to run they won't consume more than the total limit, they'll just slow down.

Essentially you are saying "only deliver power to these systems if I have enough to spare, and even then don't exceed this delivery rate".

In general this is a technique which works well when you've just researched accumulators and solar panels, but don't have enough resources to build big solar farms and accumulator farms yet.
