Modification method for low rank coal from Korea Institute of Energy Research and Korea electric power research.
The Concept of Technology
- Increase calorific value of low rank coal by drying technology
- Reducing spontaneous combustion property of low rank coal.
Key Technologies
- Fluidized bed drying technology to remove moisture from coal.
- De-watering and stabilization of low rank coal by plugging pore with small amounts of oil coating on the surface of coal.
Application
- Increase thermal efficiency in coal fired power plants(5%)
- Stable coal security for sustainable development of industry and support energy mix policy.
Advantage
- This technology is the method to reform low rank coal through heat exchanger.
Energy conservation, the conversion of low rank coal into high calorific power
Minimization the chance of moisture adsorption and spontaneous combustion
