Steam / thermal coal
Coal selected for heat or power generation against a stated energy and impurity specification.

Steam Coal
Thermal coal for power, cement and industrial heat applications, quoted to buyer specification.
Steam or thermal coal is differentiated from metallurgical and coking coal by its intended thermal use. A workable enquiry states the calorific basis, moisture, ash, sulphur, volatile matter, size and delivery basis.
Bulk supply available upon request. Source and supply available upon request.

Available types and commercial grades
The options below can be investigated against a complete buyer specification. Availability, producer, origin and conformance are confirmed in the written quotation.
Power-generation grade
Evaluated against boiler design, calorific basis, ash behaviour and permitted emissions controls.
Industrial-boiler grade
Sized and specified for the receiving plant and approved operating requirements.
Cement-plant coal
Assessed by thermal value, ash chemistry, sulphur and the plant's acceptance specification.
Typical specification points
These are enquiry fields, not published lot values. The final specification and test basis must be agreed for each supply.
| Parameter | What to define |
|---|---|
| Calorific value | State GCV or NCV, kcal/kg or MJ/kg, and analytical basis. GAR means gross as received; GAD means gross air-dried. These are not interchangeable. |
| Moisture | Specify total moisture as received and analysis/inherent moisture separately, with methods and limits. |
| Ash and sulfur | State maximum percentages and their analytical basis; add ash chemistry and fusion behaviour for the receiving process. |
| Volatile matter and fixed carbon | Specify basis and limits. Fixed carbon is calculated by difference in proximate analysis, not the same as elemental carbon. |
| Particle size | Define top and bottom screen sizes, oversize and fines tolerances, and sampling point. |
| Combustion compatibility | State boiler/kiln type, ash fusion, grindability and emissions acceptance limits. |
Packaging and supply formats
- Bulk-vessel shipment
- Containerized loose bulk
- Truck or rail movement where route and volume support it
Origin and sourcing options
Duara Group coordinates sourcing inquiries from Nairobi for African and international buyers. Tanzania, Kenya and South Africa are sourcing markets, subject to source verification. Supply through Kenya may be imported and does not establish Kenyan mine origin. Origin, current availability, assay, export eligibility and delivery terms are confirmed for the proposed shipment.
Documentation and certification
- COA and sampling basis
- Independent inspection report when required
- Certificate of origin
- Commercial and shipping documents
- Destination-specific permits and declarations
Standards and qualification
Environmental permissions, fuel acceptance and emissions obligations remain the buyer's and operator's responsibility and are not represented by this catalogue page.
Buyer requirements for quotation
- Thermal end use
- Complete analytical specification and basis
- Size requirement
- Cargo quantity
- Destination and discharge capability
- Incoterm, shipment window and inspection protocol
Commercial forms, quality and bulk procurement
Lumps, fines and dust describe particle size, not rank. Specify a screen analysis and limits on undersize and oversize. Washed coal has undergone beneficiation; washing does not guarantee a particular ash content. Sized coal has been screened. Run-of-mine material is unprocessed and may require preparation. Coal briquettes are manufactured products whose binder, strength, moisture and emissions characteristics require separate approval. Charcoal briquettes and petroleum coke are different materials.
Compare offers on a common energy basis. GCV includes heat recovered by condensing combustion water; NCV excludes that latent heat. GAR and GAD use different moisture bases. One kcal/kg is approximately 0.0041868 MJ/kg. A laboratory needs moisture and, for net-value calculations, additional composition information to reconcile unlike offers accurately.
Sourcing markets and delivery coordination
Tanzania
Inquiries can assess Tanzanian origin and regional routes against the offered coal specification. The Tanzania sourcing guide explains producing regions, source checks and transport considerations. No mine access or reserved allocation is implied.
Kenya
Supply in Kenya may involve imported coal, local traders and regional deliveries. A Kenyan supplier address does not prove Kenyan geological origin. See bulk coal procurement in Kenya for delivery and source-verification questions.
South Africa
Source assessment includes grade, exporter documentation and the specific inland and port route. See the South African buyer guide. An export terminal's capacity does not establish an individual supplier's shipping allocation.
These markets do not limit international sourcing. Quote metric-ton quantities, recurring requirements and destinations. FOB, CFR or CIF proposals must identify the named port and agreed Incoterms edition. Freight scope, inspection, insurance where applicable, customs, discharge and inland delivery responsibilities belong in the contract. No minimum order, current price, capacity or lead time is guaranteed here.
Inspection, documents and acceptance
Agree representative sampling, laboratory methods, analytical bases, inspection timing, quantity measurement and retained-sample procedures before shipment. A certificate of analysis must identify the lot and sampling point. Specify remedies for off-specification material and the controlling result if load and discharge tests differ. Confirm invoice, origin and transport documents and route-specific requirements before contracting.
Buyer questions
Can I order a guaranteed grade from this page?
Submit the required limits for assessment. Origin, availability, lot analysis, price and delivery are confirmed in the written quotation; the catalogue is not a stock offer.
What should a bulk coal inquiry contain?
Include application, coal type, GCV or NCV and basis, ash, sulfur, moisture, volatile matter, fixed carbon, sizing, metric-ton quantity, destination, named Incoterm and delivery window. Add process-specific tests for coking or PCI coal.
Can supplies repeat monthly?
State monthly tonnage, receiving capacity and call-off schedule. Recurring supply needs source and logistics confirmation and agreed quality controls for each shipment.
Supply specification
Grade, origin, packaging and order quantity are agreed per consignment. We do not publish stock or origin claims.

Frequently asked questions
How is this coal qualified for my plant?
Steam or thermal coal is differentiated from metallurgical and coking coal by its intended thermal use. A workable enquiry states the calorific basis, moisture, ash, sulphur, volatile matter, size and delivery basis.
Is stock or a minimum order guaranteed?
No. Submit your metric-ton quantity and specification. Source, availability, lot analysis, order size, price and delivery terms are confirmed in a written quotation.
What does a quality certificate need to identify?
The offered lot, sampling point and date, laboratory methods, analytical bases and tested values. Agree independent inspection and retained samples where required.
Can delivery be arranged internationally?
The source, exporter eligibility, destination requirements and freight route must be verified for the transaction. State the named Incoterm, port or final delivery point and required window.
