Good day, dear readers!
One day we may be surprised and find coal in the unpacked package that in this photo:
Coal Producer threw Cornice full kit in a bag))) How can this happen in production? Most likely firewood business at home. Such things may be carpenter's glue, varnish, polyurethane, and much more! A burn completely all at home "bouquet" of chemistry will not work!
To approach the issue of quality and harm, starting with coal production process. All the technology is simple and is based on burning through the wood without oxygen, in a scientific way - pyrolysis. If you've heard the term "gasification boilers" - a boiler having an oxygen dosing in the furnace, thereby maintaining a slow-burning feature. Here is the same.
So, the quality of coal is primarily dependent on raw materials and equipment. Equipment refers to the special retort furnaces. In these chambers the wood is heated to 500 ° C and outputted from the combustion gases are recycled as fuel and the temperature is maintained in all coal manufacturing process.
How to choose the angle?
Packages containing coal sold on every street corner. Half represented - it is of low quality coal produced in the home. In these conditions it is possible to produce coal from anything. Decided to throw the Soviet wooden bed - all in the furnace, it does not matter how many layers of lacquer. Who will be there to understand how wood - spilled into the brazier, black, well, black.
Low-quality coal is not a member of oak or birch wood, where cheap raw materials: pine, and others like it. In the best case - aspen.
Have you watched as burns through needles, or rather the resin in the pores of the wood and how long it keeps the smell of resin near the fire? When using softwood as coal - is a very high probability of separation resin vapor and settling them to the foods (bitter taste).
Unknown commodity, taken as the basis of coal in terms of production and evolved at the same toxic substances - and this is the damage caused to health.
To select high-quality coal, it is necessary to pay attention to the label or in the text of paper packaging, as in nobody will give you a look! The more data the supplier of the product and the manufacturer, the better. The law provides for at label have such products:
- business name,
- terms and rules of storage,
- data about the manufacturer,
- composition,
- date of production,
- shelf life,
- destination.
It is also necessary to pay attention to the name "Birch coal" and "Charcoal". Last, it is a 100 per cent guarantee of pine, aspen and debris as rot:
Some of the "domestic" manufacturers specify the volume instead of weight! Which clearly is not true and it is a clever move and a sure sign for you!
The ideal option would be to buy the coal in those places where taking restaurants and snack bars. Otherwise, just by trial and error, you can choose high-quality products!
But, even for longer will have to wait - it is better to give preference to proven all - firewood!
Thanks for attention!
