How to Manufacture Coal

If coal is need for steel production or other manufacturing processes, a high grade coal can be manufactured at low cost using a Coal Kiln. This type of coal burns fairly cleanly and does not contain sulphur. A Coal Kiln is built using a combination of concrete blocks with ceramic and iron walls. The Coal Kiln is a rectangular box of approximate dimensions of 20 feet long, by 8 feet wide, and 8 feet tall. On the top of the box is a chimney which can be closed with an airtight iron or steel plate. There is a door to the Coal Kiln box which is also air tight when closed. You fill the Kiln box with oak wood firewood logs which have been allowed to dry cure for 2 years in a covered wood pile. The wood is stacked inside the Coal Kiln and is soaked with kerosene as it is placed inside. The wood pile in the Coal Kiln is then lighted and allows to burn with air tight window vents on all four sides which are iron or steel plates which can be closed. The wood pile in the Coal Kiln is allowed to burn to a roaring flame for one hour, and then the door, the window vents, and the chimney are closed air tight. The wood fire in the sealed Coal Kiln is allowed to smolder burn until the fire extinguishes on its own. This may take one month. The door is then opened and the wood turned to coal is then removed.
Also, given this situation, coal mining can be ended and converted to coal bed methane natural gas production.
