Fuel
Fuel can be inserted into burner devices and burned to power them. Different types of Fuel provide different amounts of energy, measured in megajoules (MJ). A megajoule (MJ) is equivalent to one megawatt second (MWs), so dividing the megajoule (MJ) value by the power consumption in megawatt (MW) gives the time the fuel will last.
Types
This is a list of all Items usable as Fuel in burner devices, ordered by fuel value:
| Item | Fuel value | Fuel value per raw total |
|---|---|---|
 |
2 MJ | 4 MJ per raw wood |
 |
4 MJ | 4 MJ per raw wood |
| |
6 MJ | 3 MJ per raw wood |
 |
8 MJ | 8 MJ per coal |
| |
25 MJ | 20 MJ per unit of Crude oil * |
| |
4 MJ | 4MJ per raw wood |
 |
225 MJ ** |
(*) This assumes the Crude oil is processed completely into Solid fuel, using Advanced oil processing and Heavy oil cracking as intermediate steps, but not Light oil cracking. Less efficient methods are possible. In practice, the Petroleum Gas part of processed crude oil is more likely to be used for something other than Solid fuel.
(**) Note that through version 0.12.35, Rocket fuel is not Fuel and cannot be used in burner devices.
