Composition and Varieties of Coal
Coal is an ancient type of solid fuel that our ancestors used to heat.
The basis of combustibility is carbon in the composition of various organic elements, which are divided into solid and volatile.
Volatile substances during the ignition of coal evaporate with smoke. With a large amount, it is easier to ignite coal, but at the same time it burns faster. The content of these elements ranges from 8-40%.
Solid combustible elements differ in density. Often, the higher the density, the higher the heat capacity of coal. The density of substances in various grades of coal is 1.3 -1.7 g/cm3.
Non-combustible substances are elements that form ash. The mineral components of coal do not burn in household stoves, from which waste is generated. A large amount of ash reduces the calorific value of coal. The percentage component of these substances reflects such a characteristic, called ash content. On average, this figure is 5-30%.
Sulfur is the next non-combustible substance that can be found in coal. This element harms the environment due to the formation of sulfur oxide in the atmosphere, followed by the formation of sulfuric acid, and can also lead to the destruction of metal components of equipment. The quantity differs in different grades of coal. The level of sulfur that is safe for use in household equipment is 0.1-1%.
Moisture is the last component of coal, it negatively affects the calorific value of coal. A smaller amount of moisture is contained in the older coal.
Coal loses most of its moisture during coalification and becomes much denser. The content of volatile substances decreases, and the calorific value increases. As a result, coal of old origin, which is considered to be anthracite, is more efficient as a solid fuel for the boiler, from which the price of anthracite grade coal will be higher.
Coal Fraction / Size Class
This is a size specification. There are several main classes, depending on the size of the unit of coal in millimeters. It is also possible to buy coal for the furnace of mixed classes.
Our main product is the most convenient fraction 10-25 Ecopeas, there is also a nut 25-50.
All coal that can be bought from iPELLET at the best price in Poland with delivery is of the highest quality without dust.
Coal packaging
Coal can be in bulk in a dump truck, we can also pack it in 25 kg bags and put it on pallets of 1 ton. Packing in big-bags on 1 ton is possible.
