Valid fuel

The boiler uses fuel to convert water into steam at 165°C suitable for use in a steam engine. It has two water connectors on opposite ends and passes water through to adjacent equipment such as other boilers. The boiler features a single output for the steam it produces. It only consumes fuel as it creates steam. Boilers used in conjunction with offshore pumps and steam engines are a vital part of early power generation.

For each unit of water, 10 units of steam are produced. Inserting one coal (4 MJ) into a boiler then using the resulting steam in a steam engine will supply 4 MJ of energy to an electrical system. It costs 30 kJ to heat 1 unit of water to steam at 165°C, so one boiler will produce 60 steam per second.

Inserters can insert fuel into boilers. However, using powered inserters to move fuel into a boiler can be problematic should fuel become unavailable: if no power is being produced, then powered inserters fueling a boiler cannot operate. Using at least one burner inserter, which uses fuel and not electricity, ensures that at least one inserter is available to restart a single boiler. Inserters can also remove fuel from boilers, allowing inserters to move fuel down a chain of boilers.

Optimal Ratios

1 offshore pump + 180 Electric mining drills > 200 boilers > 400 steam engines. (Total of 360 MW)

History

• 2.0.0:
  • Decreased water use by 10x, changing the water:steam ratio from 1:1 to 1:10.

• 0.15.10:
  • Steam became a separate resource, boilers now produce steam rather than high temperature water that is displayed as steam
    • This distinction is meaningful for circuit network accounting of steam and the coal liquefaction recipe

• 0.15.0:
  • New graphics.
  • Changed boiler dimensions to 3×2.
  • 'Steam' is produced on a separate connector rather than heating water passed through.
    • At this time, steam is actually water that is renamed when over 100 degrees.
  • Significantly increased energy consumption/production.

• 0.13.0:
  • New fire graphics for boilers.

• 0.9.2:
  • Enabled the inserter to take fuel out of boilers.

• 0.8.0:
  • Flickering light added to furnaces and boilers.

• 0.6.1:
  • Boilers show their fuel inventory in the entity info.

• 0.5.1:
  • Boilers are now fast-replaceable with pipes.
  • New boiler graphics.

• 0.1.0:
  • Introduced
