Coal supply. The 1,320MW thermal power project is estimated to use of blended coal (70% domestic coal and 30% imported coal) a year. The domestic coal for the plant is sourced from NTPC's captive coal block Pakri Barwadih in Jharkhand. Pakri Barwadih is the first captive coal mine of NTPC that commenced commercial production in April 2019.

The finer the grinding of coal, the more efficient its combustion. The difference is that the highenergy ignition devices which generate sparks replace people's hands. The heart of a pulverized coalfired boiler is the pulverizer, also known as the mill • Use: Pulverized coal can be used as a reducing agent by injecting it through the tuyeres.
