Description

Coal Antracite (Total Dust) is a finely divided, high-carbon anthracite coal dust characterized by its low volatile matter and high fixed carbon content. This material is valued for its exceptional calorific value and consistent chemical composition, making it a reliable and efficient solid fuel source. It is primarily utilized in industrial processes requiring intense, stable heat generation, such as in metallurgical applications, cement production, and as a carbon additive.

Application

• Metallurgical Fuel: Used as a high-efficiency carbon source and heat provider in foundries, ferroalloy production, and other metal smelting operations.
• Cement & Lime Kiln Fuel: Serves as a primary or secondary fuel in rotary kilns due to its high heat output and low ash content.
• Carbon Raiser/Additive: Added to molten iron in cupolas and electric arc furnaces to adjust the carbon content and improve metal properties.
• Industrial Boiler Fuel: Provides efficient combustion in specialized industrial boilers for steam and power generation.
• Sintering Process Fuel: Employed in iron ore sintering plants to agglomerate fine ore particles into a usable blast furnace feed.
• Activated Carbon Production: Acts as a high-quality raw material precursor for manufacturing activated carbon through controlled activation processes.
• Water Filtration Media: Used in specific filtration systems as a component for removing impurities from water and wastewater.
• Soil Amendment: Applied in agriculture and horticulture to improve soil structure and carbon content in certain contexts.

Quality Control

Our Coal Antracite (Total Dust) is sourced and processed under strict quality protocols to ensure batch-to-batch consistency and performance. Quality is verified through analysis of key parameters including fixed carbon, volatile matter, ash content, sulfur, and calorific value. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and production planning.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from sources of ignition, heat, and incompatible materials. Keep containers sealed when not in use to minimize moisture absorption and dust generation. Observe all local and national regulations for the storage of combustible dusts.
