High Energy Bituminous Coal Ideal for Power & Industrial Boilers ≥6, 500 Kcal/Kg

Product Description

HighEnergy Bituminous Coal (≥6,500 kcal/kg)

Theme: Efficient & Clean Industrial Fuel

Highenergy bituminous coal (6,500 kcal/kg) is a premium grade of bituminous coal known for its high calorific value, low ash and low sulfur. It is widely used in industrial boilers, kilns, power generation and coal chemical industries. Its stable heating value and good combustion characteristics make it an ideal choice for industrial users pursuing energy efficiency and environmental compliance.

 

Product Overview

This highenergy bituminous coal is a toptier steam coal. Its net calorific value (as received, NAR) reaches ≥6,500 kcal/kg - significantly higher than typical steam coal (5,000-5,800 kcal/kg). For the same weight, it releases more usable heat, helping users reduce fuel consumption and transportation costs while lowering carbon emissions per unit of output.

 
 

Key Technical Specifications

 

 

Parameter	Typical Value	Remarks
Net Calorific Value (NAR)	≥ 6,500 kcal/kg (≈27.2 MJ/kg, 11,700 BTU/lb)	Core pricing basis, determines combustion efficiency
Volatile Matter (Vdaf)	28% - 38%	Moderate VM, easy ignition, stable combustion
Ash Content (Ad)	≤ 10%	Low ash, reduces slag and dust emissions
Total Sulfur (St, ar)	≤ 0.8%	Low sulfur, meets environmental regulations, reduces SO formation
Total Moisture (Mt, ar)	≤ 12%	Low moisture, high effective heating value
Fixed Carbon (FC, daf)	≥ 55%	Main source of sustained heat
Size	0 - 50 mm (customizable)	Slack coal or mixed sizes, adaptable to different combustion equipment

Note: Typical values are shown above; specifications can be adjusted per customer requirements.

 

Main Applications

• Industrial Boilers & Kilns
  Used in industrial boilers (chemical, paper, textile, food industries) and kilns (cement, lime, ceramics). High calorific value provides faster temperature rise and stable furnace control.

• CoalFired Power Plants
  Blended or fired alone in pulverized coal boilers and circulating fluidized bed boilers, improving generation efficiency and reducing coal consumption.

• Metallurgical Industry
  Suitable as pulverised coal injection (PCI) for blast furnaces, replacing part of the coke. Some highquality lump coal can also be used to produce metallurgical coke.

• Coal Chemicals & District Heating
  Applicable for coal gasification, lowtemperature carbonisation, and as a highquality fuel for largescale central heating boilers.

 

Product Advantages

 High heating value - cost effective
Releases much more energy per tonne than ordinary coal grades, lowering coal consumption per unit of steam or electricity.

 Low ash & low sulfur - environmentally friendly
Ash ≤10%, sulfur ≤0.8% significantly reduce boiler slagging, fouling and flue gas desulfurisation load, meeting tightening emission standards.

 Stable combustion - high adaptability
Moderate volatile matter gives easy ignition and a long flame. Suitable for chain grate boilers, pulverised coal boilers, circulating fluidised bed boilers and other furnace types.

 Reliable supply - adjustable size
Can be crushed and screened according to customer requirements (e.g. 0-25 mm, 0-50 mm), convenient for storage and coal feeding.

 

 

Purchasing & Usage Recommendations

1. Check the quality inspection report
   Always rely on a report from an independent, accredited thirdparty laboratory. Focus on net calorific value (as received), ash, sulfur and moisture.

2. Clarify the calorific value basis
   In international trade, net calorific value as received (NAR/ARB) is commonly used for settlement. Some documents may quote gross calorific value (GAR/ADB). Confirm which basis is stated in your contract.

3. Proper storage management
   Bituminous coal stored for long periods is prone to spontaneous combustion. Control stack height, monitor temperature regularly and ensure good ventilation. Cover outdoor stockpiles to prevent rain.

4. Environmental compliance
   Even with lowsulfur coal, dust collection and desulfurisation equipment are recommended to ensure flue gas emissions meet local standards.
