Physical Characteristics & Content
- Color & Texture: Jet black, hard, dense, and glassy luster when exposed to light.
- Moisture Content: Very low (low moisture), preventing it from molding or self-combusting when stockpiled.
- Carbon Content: Highly rich, resulting in very minimal residual ash content after combustion.
-
Key Advantages
- Highly Efficient: Requires a much lower volume of coal to generate the same heat temperature compared to low-calorie coal.
- Machinery Friendly: Stable combustion temperatures protect factory boiler performance from rapid wear and tear.
- Low Pollution: Produces significantly fewer flue gas emissions and waste ash.
-
Primary Applications
- Heavy Industry: Essential fuel source for steel smelting plants, cement production, and chemical industries.
- Power Plants (PLTU): Utilized in modern power plants with Supercritical technology that requires extreme heat pressure.
- Export Commodity: Serves as Indonesia's flagship product for export to advanced industrial nations such as Japan, South Korea, and Taiwan.
