Thermal Coal (steelmaking support)

Description

1. Product Overview

This product is a high-calorific, medium-to-low volatile thermal coal specifically engineered for industrial combustion systems requiring sustained heat output and stable ash characteristics. Its primary industrial use is as a dedicated fuel source for pulverized coal injection (PCI) in blast furnace steelmaking, as well as for captive power generation within integrated steel plants. The key value proposition is a consistent baseload energy solution that reduces coke consumption per ton of hot metal, directly lowering steel production costs. Strategically, it is critical for steelmakers navigating margin compression, offering a supply-side lever to optimize the blast furnace energy balance amid volatile coking coal markets.

2. Key Specifications & Technical Characteristics

• Chemical Composition:

  • Calorific Value (ARB): 5,800 – 6,200 kcal/kg

  • Total Moisture (ARB): ≤ 12%

  • Ash Content (ADB): 9% – 12% (low-slagging design)

  • Volatile Matter (ADB): 24% – 30% (optimized for PCI ignition)

  • Sulfur Content (ADB): ≤ 0.8%

• Physical Characteristics:

  • Form: Crushed / washed thermal fines

  • Particle Size: 0 – 50 mm (90% passing, suitable for milling)

  • Hardgrove Grindability Index (HGI): 45 – 55

  • Ash Fusion Temperature (reducing atm): >1,250°C

• Packaging Options: Bulk vessel (hold loading) / Untippered 1.5MT big bags on demand

• Shelf Life: 24 months (dry storage, avoid spontaneous combustion monitoring)

3. Core Industrial Applications

• Primary Industries: Integrated steel manufacturing, ferroalloy production, cement (co-processing)

• Specific Operational Use Cases:

  • PCI in Blast Furnaces: Injected via lance to replace 20-40% of metallurgical coke, lowering coke rate by 80-120 kg per ton of hot metal.

  • Sinter Plant Ignition: Uniform combustion for iron ore sintering, reducing fuel oil dependency.

  • Steel Plant Captive Power: Fluidized bed or pulverized coal boilers for on-site electricity and steam.

• Performance Advantage: Compared to standard thermal coal, this grade delivers lower ash adhesion on tuyeres and a predictable volatile release profile, preventing pressure fluctuations in PCI systems. Cost advantage: $12–18/MT savings versus blending low-volatile coking coal fines.

4. Competitive Advantages

• Quality Consistency: Statistical Process Control (SPC) at load port; each shipment includes a certified mill test report (ISO 17025 lab).

• Supply Reliability: Dedicated production allocation from two adjacent mines (5-year reserve life); force majeure risk <2% annually.

• Logistics Capability: Dedicated rail loop to deep-water terminals; typical load-to-sail in 72 hours.

• Pricing Competitiveness: Index-linked pricing (API2 or Platt’s PCI index) with a flat logistics pass-through; no hidden demurrage recovery.

• Sustainability & Compliance: Low mercury (<0.1 ppm) and chlorine (<0.05%). Supplier holds ISO 14001 and EU CBAM-ready emissions documentation.

• Technical Support: Free combustion modeling service for your injection lance configuration; quarterly ash fusion advisory.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20,000 MT (one Panamax-sized cargo lot)

• Loading Capacity per 20FT Container: Not applicable (product shipped in bulk). For bagged option: 25 MT per 40FT open-top container (1.5MT bags × 16–17 bags).

• Typical Dispatch: FOB (loading port – Richards Bay / Newcastle / Kalimantan) or CIF any major steelmaking hub.
