We distribute lignite mined in Czech Republic, in Severoceske doly – Bilina , Ledvice and Most – Komorany. We offer the whole range of this type of coal available in rail and car delivery. We also conduct sales of lignite from Ukraine.
What is lignite?
Lignite is a sedimentary rock created of piled dead plant fossils. Carbonation of fossils took place probably in Cenozoic (Tertiary period) and was possible because of lack of atmospheric oxygen. The rock constitutes of 62-76 per cent of elemental carbon.
Types of lignite:
Lignite sales includes distribution of its several types. Granulation allows to divide the rage into several types:
- Billets (600-80 mm)
- Coal dust (20-0 mm)
- Nut coal (80-20 mm)
- Coarse (600-40 mm)
- Fine (40-0 mm)
- Medium (300-0 mm)
- Unsorted (600-0 mm)
Lignite may also be divided into hard and soft. The firs one is mined in strip mines and its calorific load equals ca. 4165 kcal/kg. Hard lignite is mined in regular mines and its energy load is higher: from 4165 to 5700 kcal/kg. „Calorific load” is a term which can be explained as calorific value. The higher number it shows, the more heat can be obtained in the process of burning. Calorific load marks the quality and effectiveness so important for citizens of Poland.
What are the advantages of lignite?
Lignite is an important feedstock for chemistry industry. It also works well as soil for gardening because it enriches the natural soil in minerals. But most of all it is the best and the most economic source of power and heat. Let's take a short look on the advantages of lignite.
- Price - lignite is not an expensive, but rather cheap source of energy. Great economic solution are widely available on the market furnaces with charging feeders which provide constant automatic input of appropriate amount of coal and release people from mess and dirt.
- High calorific content - lignite is an extremely economic source of energy. Even a small amount gives lots of energy. Lignite burns slowly thus provides heat for low relatively long period of time.
- Availability – even if coal is not a renewable source of energy, it is still widely available. Easy to purchase, especially in the autumn-winter period.
