What Are Coal Fines?

Coal fines are tiny coal fragments and fine dust produced when coal is crushed, screened, or processed. Specifically, -5 mm washed and screened coal fines consist of particles no larger than 5 mm and often undergo treatment to reduce ash and impurities.

Our coal fines have a calorific value (CV) of 21 MJ/kg, placing them in the category of high-quality steam coal. This energy content is measured using standard methods (e.g. bomb calorimetry) that consider moisture and ash. 

Blending to Meet Calorific Targets

Adding -5 mm coal fines (21 MJ/kg CV) allows you to blend with higher-value coals (CV 27–30 MJ/kg). This helps you:

• Achieve precise energy specifications for power plants or industrial processes

• Reduce ash and sulfur content when compared to blending higher-sulfur coals

Controlling the blend ensures compliance with energy and environmental standards.

Low Sulfur: Cleaner & Cost‑Effective

Coal fines typically contain low sulfur, offering key benefits:

• Lower SO₂ emissions: Meets stricter environmental regulations 

• Reduced operating costs: Less need for flue-gas desulfurization (FGD) systems

• Extended equipment lifespan: Less sulfur corrosion in boilers and pipes

• Greater market appeal: Low-sulfur coal is often preferred and commands higher prices

Additional Benefits of Coal Fines

• Resource Utilisation: Repurposing processing by-products reduces waste and boosts efficiency 

• Enhanced Combustion Control: Small particle size improves combustion uniformity, provided safety concerns (e.g. dust control) are addressed

Ideal Applications

By blending these -5 mm coal fines, you get:

1. Tailored fuel quality (CV, sulfur, ash)

2. Compliance with environmental guidelines

3. Cost savings on emissions control

4. Improved boiler operation and reduced downtime

This makes them valuable for power generation, industrial heating, cement production, and metal smelting.
