Charcoal Kiln is a Production Building which produces 
Coal from undeveloped tiles within a small radius of influence around it. The building requires these tiles to be wooded, but the Charcoal Kiln will plant its own trees if there are not enough trees. It can be built in the Old World (and Cape Trelawney), or in The Arctic where it requires forest fertility, or in the New World with 
Empire of the Skies DLC or 
New World Rising DLC. It is also the only production building in the Arctic that does not require heating and it has a vital function, providing coal to supply the heaters.
When charcoal kilns are placed in a lush forest they can start operating immediately. Otherwise trees have to be planted first, which can take from 15 seconds up to 5 minutes based on how many trees are in the influence radius. The exact waiting time is shown when placing the building, after that time the kiln will begin to produce coal while planting new trees at the same time - thus never running out of trees (if no new buildings or roads are built in the influence radius). The initial planting phase can also be sped up by using appropriate tree painter before placing the charcoal kiln.
Productivity[]
It takes 30 seconds to produce 1 ton of coal so the production rate is 2 tons of coal per minute. Productivity can be changed in the Old World and New World by adjusting working conditions and using items and electricity. In the Arctic only items can alter productivity.
Charcoal kilns do not need their whole influence radius to be free of other buildings and roads, only 227 tiles (out of 352 in the whole radius) have to be free to achieve 100% productivity. If less number of tiles is free, the productivity drops according to the amount of occupied space.
Coal is an important resource obtained either from charcoal kilns or coal mines. Coal mines are twice as productive as charcoal kilns and do not lower the attractiveness of an island so charcoal kilns should be used only to make up for not having enough coal deposits.
Production Chains[]
All regular production chains which utilise coal are listed below. Most chains include coal mines instead of charcoal kilns - but coal mines can be easily replaced with twice as many charcoal kilns.
