coal pipes and burner nozzle sizes is essential for the best furnace performance. Furthermore, remember that there will be minor variation in mill capacity, fuel quality, and mill inlet airflow rates that must be considered when sizing the pulverizer throat flow area. The vertically flowing air must be of sufficient velocity to sus
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.
