The Coal Boiler is the first unlocked machine with the ability to create File:SteamHigh.png High Pressure Steam. It plays an important role in the Distillation of 
Crude Oil. Additionally it provides the first alternative Power Production method to the 
Diesel Generator: The File:High-pressureTurbine.png High-Pressure Turbine, which uses
File:SteamHigh.png Steam (High) to create mechanical energy, which can be converted to Electricity.
Later in the research tree additional recipes are unlocked which allow the use of 
Woodchips, 
Biomass, and File:AnimalFeed.png Animal Feed as sustainable alternatives to Coal.
Recipes
Below are all the recipes, which this building is capable of producing. Note, that some of them may be locked behind Research, and not immediately available in your game.
