Rourkela Steel Plant launches state-of-art coke oven battery

Rourkela Steel Plant (RSP), a unit of SAIL, on Friday commenced coke pushing from a new state-of-the- art coke oven battery. Its coal handling plant and coal chemicals unit also became operational concurrently, announced Rourkela Steel Plant.

The new Battery No 6, the second of its kind in SAIL, is top charged having compound twin flue, under jet, regenerative heating with partial recirculation of waste gases. The 7 metre tall battery of 67 ovens will produce run of oven Coke (Dry) of 0.768 mt a year.

The computerised heating control system (COHC) has been installed for the battery operation for the process management system to improve reduction in environmental emission, improve coke quality and productivity.

Rourkela Steel Plant sources said that with the ongoing modernisation and expansion, the plant is all set to double its capacity and augment it from the current level of 2 million tonnes per annum (mtpa) to 4.5 mtpa of hot metal.

Crude steel making capacity will simultaneously increase from the level of 1.9 mtpa to 4.2 mtpa and production of saleable steel will zoom from the level of 1.671 mtpa to 3.99 mtpa.

Apart from the new Coke Ovens Battery No 6, two more key units — New Sinter Unit and Raw Material circuit of Ore Bedding and Blending Plant Phase-II — have already been made operational and are in the process of stabilisation.
