Anthracite coal

In the modern world and, specifically, in our country, rapid changes are taking place in all spheres of life. This was especially noticeable in the thermal power industry and heat generation. The multiple increase in gas tariffs and the need for enterprises to switch from the anthracite group to other types of fossil coals have created a situation for all other heat consumers in which even a normally wealthy person will think many times before choosing some kind of energy source. Although the choice is quite diverse, but still everyone determines for himself some ceiling of the cost for the consumed heat. This is especially true for those who have autonomous heating and can really choose what to use as fuel when the need arises. This is also true for boiler houses, mini-boiler houses in housing and communal services, educational institutions, medical institutions and other heat generating enterprises that have to measure their heat needs and their budget for this article.

We have been on the solid fuel market for a long time and regularly conduct a comparative analysis of the cost of heat from various types of fuel. Therefore, before making a choice, we recommend that our customers and partners familiarize themselves with our data, which take into account prices in this industry and which we update periodically.

Anthracite coal

As everyone knows, fossil coals are divided by age and depth of occurrence - hence the various methods of mining (open, closed). But the most important thing is the properties and characteristics of various types of coal. It is the composition of coal and its properties that determine the breadth of its areas of application and, accordingly, the demand and the volume of production (consumption). Anthracite is considered to be the most popular of all coals.

Anthracite differs from other types of coal with high quality characteristics and unique properties.

This is a low humidity, low content of volatile compounds and sulfur, but at the same time, the highest content of fixed carbon is from 91 to 98%. It is because of the high carbon content that another distinctive feature of anthracite is the very high specific heat of combustion. This type of coal burns practically without flames and smoke, releasing a large amount of heat (up to 8000 kcal / kg).

<>Due to these properties, anthracite has been and remains an indispensable fuel in various spheres of human activity: in production, for blast furnaces, for electric and thermal stations, for boiler and mini-boilers, for municipal needs, as fuel (for ships and locomotives) etc. Also, this type of coal is widely used by the population for various domestic needs.
