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.
