Coal
At Krona Impulse, we provide quality coal supplies (Anthracite, G, DG) in various fractions, accommodating both domestic and international clients on terms DAF, EXW, FOB, FCA. Our portfolio includes enriched coal and dry sieving, rendering us a versatile coal supplier.
With its high energy yield, coal is a reliable fuel for solid fuel boilers and stoves, used extensively in municipal boiler rooms and industrial enterprises. Its universal utility and convenient transportation, coupled with its ability to generate heat during combustion and smoldering, make it a go-to fuel for private homes and industries alike.
In the face of fluctuating energy prices, coal stands out for its stable cost, which remains lower than that of gas or liquid fuels. Further, its significant heat transfer means small amounts sufficient to maintain comfortable temperature levels, even during severe cold.
The quality of our coal is gauged using three key indicators: calorific value, ash content, and moisture. Anthracite coal, with a calorific value of 8600 kcal/kg, is ideal for domestic use. The ash content in our high-quality varieties remains under 25%, optimizing fuel efficiency and reducing cleaning frequency. We also take into account both internal and surface moisture to ensure you receive the best quality coal.
