In the West, almost all grocery store bags are sold with charcoal. Coal is gaining popularity as well as around us. Buy not only ordinary citizens for the sake of giving (grilled skewers), but as well as almost all the barbecue as well as restaurants.
According to conversations with his friends realized that it would buy the majority, but certainly did not know where. In general, there is a shortage of the product of pyrolysis of wood.
I began to study this question. And also this is the result of this study.
In the old charcoal is not the least needed in the smithy, in smelters, and medicine. Produced its set in the villages and sold in the city. There was a whole industry of charcoal production. The process of creating a very simple, but important was the experience. Evolved a special way a lot of logs, the size of a stack of hay, covered with turf and ignited. Output of coal - about 25-30%. At the present time, experience a similar process of creating or lost, or someone in such a case kept secret. After all, any way form an angle there!
Looked through old books, found the scheme of the stove on wheels, consisting of an impressive loading barrels and a small furnace. Yield - 60%.
Is again a more simple variation (cottage) - the boot well, along with the flue pit. Pit closes iron sheet.
Now the math: 1 cubic meter birch wood costs 800 rubles. (Including delivery) to dig a pit for yourself sheet of rusty iron drag from the landfill. Rent is not of course (about himself in the country). Electricity is not wasted. Even at 30% yield, we obtain about 300 kg of coal. Wholesale value - 10 euro / kg. 1 restaurant consumes 3.5 tons of coal in the moon. However, further - consider yourself!
