Blending of Coals in Power Stations Bright Hub Engineering

Considerations for Coal Blending in Power Stations. The low-grade coals can be mixed with better grade coal without deterioration in thermal performance of the boiler, thus reducing the cost of generation. In many nations, the blending of high grade imported coal with low grade high ash coals has long been adopted. Many methods may be used.
