Coal is a solid sedimentary rock. It is formed during the decomposition of the remains of certain plant species and is the most important mineral that has been mined for nearly a dozen centuries. By the way, earlier for the formation of this solid substance a number of conditions were required. Plant material, which is formed as a result of decomposition of plants, must accumulate much faster than the process of decomposition and subsequent decay. Therefore, coal was formed mainly in the open spaces of ancient peat bogs. It was there that, in the absence of oxygen in the required volume, carbon compounds accumulated. Since peat was used as fuel at that time, it was an excellent material for the formation of coal.
Coal, as indicated above, is a carbon substance. In addition to this “aromatic” compound, water and other impurities are present in the rock. A very important indicator of the value of coal is the maximum amount of heat that is released during its combustion. A good example is the usual wood log. Have you tried to kindle raw firewood? As it turns out? Until all the moisture has evaporated, it is almost impossible to light a fire. In addition, while moisture interacts with heat, volatile substances are formed that prevent fire. The same thing happens with coal. For the most efficient use of heat during combustion, coal must be of high quality. Its value and the possibility of further application depend on this.
Its deposits are, as a rule, located at great depths. The highest quality grade of coal is anthracite. It is mined in mines at a depth of 2000 m or more. Some rocks are less deep, so the deposits are mined in an open way. Simply put, they are developing big careers.
Coal is used as solid fuel. It can be used in everyday life as energy fuel, as well as in the chemical and metallurgical industries. It can be converted into oil, which allows you to eventually get liquid fuel.
The coke industry is widespread in our country. When coking, products such as gas, ammonia, coal tar appear. In turn, gas can produce toluene, benzene, which is widely used in the rubber industry, and is also part of varnishes and paints used in our daily lives. In addition, the raw materials obtained from coal processing are used in the production of building materials, ceramics and various types of abrasives.
No less useful material involved in human life is coconut charcoal. In its properties, it is significantly superior to wood. This type of coal is made using a special technology - from coconut shell. It is characterized by a higher burning temperature and smoldering time, compared with similar products on the market.
Coconut charcoal is mainly used for cooking on the grill or grill. Recently, hookah adherents have begun to take an active interest in him. Due to its features, it is very economical to use. Good heat dissipation and the absence of harmful impurities make it a very popular and popular source of energy.
The cost of coal, both coconut and stone, depends on many factors. A special place is, of course, the pricing policy of a particular type of product. But still, the end consumer is interested in quality. And it is not so important how it will be confirmed by the warmth and comfort in the house or a perfectly cooked barbecue.
