The '''boiler''' is used to convert [[water]] into [[steam]]. When [[fuel]]ed it converts feed water into steam at 165 degrees, matching the maximum temperature of the [[steam engine]]. Boilers have 2 water connectors, allowing them to pass water through to other adjacent equipment, but only 1 steam connector for output.

1 unit of steam is produced for each unit of water. Fuel is consumed at 50% efficiency, which means that a single unit of [[coal]] (8MJ) fed into a boiler and then utilised in a steam engine will result in 4MJ of energy added to an electrical system. It costs 30kJ energy to heat 1 unit of water to steam at 165C, so one boiler will produce 60 steam per second.

Boilers are the main source of pollution in the early and midgame.

== Inserters can pull from boilers ==

[[Inserter]]s can place (fuel) items into boilers, but can also remove items from them. See [http://www.factorioforums.com/forum/viewtopic.php?f=8&t=6008&start=30#p64343 this post] and follow ups.

This can be also used to create an early filter-device, which filters only fuel items: One inserter inserts into a boiler (not connected to water), another removes the items.

'''Steam''' is a [[fluid system|gas]] created by heating water in a [[boiler]] or [[heat exchanger]]. After being distributed via [[pipe]]s, steam can be used to generate electricity via [[steam engine]]s and [[steam turbine]]s. Steam is also used in [[coal liquefaction]] in [[oil refinery|oil refineries]]. Since steam is a fluid, it can be stored in a [[storage tank]].

== Power generation ==
The amount of energy contained in steam is linearly proportional to it's temperature (minus 15°C ambient temperature). The energy storage of steam is exactly ''200 Joule / unit / degree Celsius'', so for every degree increase in temperature of a single unit of fluid requires exactly 200 Joules.

In all cases, steam produced in boilers is 165°C and steam from heat exchangers is 500°C. This higher temperature equates to a higher energy density of the same number of units of steam, meaning: higher temperature, more energy per volume. Steam suffers no thermal losses sitting or flowing through [[pipe]]s or [[storage tank]]s, the energy put into water to create steam is the same amount of energy you get back out from it since both steam engines and turbines are 100% efficient. (Note: a boiler is only 50% efficient at generating steam!)

For example, a storage tank which holds 25000 units of Steam at 165°C contains...
<pre style="width: 68%;padding-right: 0em;">(200 Joule / unit / Celsius) * 25000 units * (165°C-15°C) = 750 000 000 joules = 750 MJ </pre>

A storage tank holding 25000 units of Steam at 500°C thus contains 2.425 ''giga''joules of energy, a surprisingly large amount equal to 485 fully charged [[accumulator]]s!
(200 Joule / unit / Celsius) * 25000 units * (500°C-15°C) = 2 425 000 000 joules = 2.425 GJ

It's obvious a steam engine or turbine taking in steam that's colder than it's maximum temperature will not be able to produce full power. When this happens, power generation is limited by the maximum fluid consumption rate of the machine.
When a steam engine is fed steam hotter than it's maximum temperature, the power generation is limited to the maximum (900 kW) output of the machine and merely consumes less steam for the same energy output. This does not mean higher generation efficiencies are attained. Steam engines are perfectly usable on a 500°C nuclear power plant, they merely use more space than a turbines for the same amount power. Vice-versa, turbines are usable in 165°C boiler circuits as well.
