Trade Products_COAL - The Most Significant Source for Power Generation
COAL is the most readily available natural resource that is in abundance and an extremely cost effective source of energy.
High Rank Coal : Bituminous, Anthracite (High Energy Content
& Low Moisture)
Low Rank Coal : Peat, Lignite, Sub-bituminous (Low Energy Content
& High Moisture)
Low Rank Coal | ||
1. | Brownish-black in colour and has a carbon content of around 25-35%, a high inherent moisture content sometimes as high as 66% | |
2. | Low energy density and typically high moisture content. Unfortunately its high moisture content and susceptibility to spontaneous combustion it can cause problems in transportation and storage. | |
3. | Low heating value, high handling cost and spontaneous combustion but contain low sulfur and low ash contents . | |
Potential of Low Rank Coal | ||
1. | Low rank coal can be efficiently and economically processed to yield a higher-grade and higher heating value. | |
2. | Enormous increase and economic benefit on the energy supply. | |
3. | Reducing Environmental impact | |
Coal Enhancement has to be | ||
1. | Economical | |
2. | Address the issues of Spontaneous combustion | |
3. | Reducing Moisture permanently |
Expenergy Technology
1. | Enhancing the calorific value of the low grade
coal by reducing the moisture content. |
|
2. | TM reduced to near IM level. | |
3. | Minimal equipment needed. |
|
4. | Fast set up time. |
|
5. | Low cost and high margin. |
