Black Cmc Solid Lumps Indonesian Coal, For High Heating, Steaming, Purity : 90%, 99%

Indonesian coal is a type of thermal coal that is mined in Indonesia. It is a high-quality coal with a low sulfur content, making it a desirable fuel for power generation.

The specifications for Indonesian coal vary depending on the type of coal, but some general specifications include:

• Gross calorific value (GCV): 5500-6500 kcal/kg
• Ash content: 5-7%
• Volatile matter: 38-42%
• Fixed carbon: 40-44%
• Sulphur content: 0.5-1.0%
• HGI (Hardgrove Grindability Index): 50-70
• Size: 6-20 mm

The GCV of Indonesian coal can range from 5500 to 6500 kcal/kg, with a typical value of 6000 kcal/kg. This makes Indonesian coal a high-quality fuel with a high heat output. The ash content of Indonesian coal is also relatively low, typically ranging from 5 to 7%. This makes Indonesian coal a cleaner-burning fuel than some other types of coal.

The volatile matter content of Indonesian coal is 38-42%. This means that Indonesian coal has a high energy content, but it also produces more ash and sulfur dioxide when burned. The fixed carbon content of Indonesian coal is 40-44%. This means that Indonesian coal has a high energy content and produces less ash and sulfur dioxide when burned.

The sulfur content of Indonesian coal is typically 0.5-1.0%. This is a low sulfur content, making Indonesian coal a desirable fuel for power generation in countries with strict emissions regulations.

The HGI of Indonesian coal is 50-70. This means that Indonesian coal is relatively easy to grind, making it a good choice for power plants that use pulverized coal boilers.

The size of Indonesian coal is typically 6-20 mm. This size is suitable for use in power plants and other industrial applications.

Overall, Indonesian coal is a high-quality thermal coal with a low sulfur content. It is a desirable fuel for power generation in countries with strict emissions regulations.
