How to do Coal Selection for Power Generation?

There are several factors by which we can select a proper type of coal for power generations, those factors are –

1. Calorific Value: High calorific value coal generates more energy per unit, making it good for power generation.
2. Sulfur Content: Low sulfur concentration reduces SO₂ emissions and reduces acid rain.
3. Moisture Content: Lower moisture level is recommended since higher moisture content affects coal’s energy efficiency.
4. Ash Content: Low ash level is preferable since high ash content can result in increased residue and disposal concerns, as well as reduced combustion efficiency.
5. Fixed Carbon: High fixed carbon concentration indicates higher energy content and more efficient combustion.
6. Technological Compatibility: The coal must be suitable for the power plant technology (e.g., pulverized coal combustion, fluidized bed combustion).
7. Economic Considerations: The cost of coal, transportation logistics, and availability are all important considerations in the choosing process.
