Visakhapatnam, Jul 5 : State-owned Rashtriya Ispat Limited, the corporate entity of Visakhapatnam Steel Plant (VSP) on Friday commissioned its fifth Coke Oven Battery (COB-5) project complex, which was constructed along with the existing batteries at an estimated cost of Rs.2,500 crore with a production capacity of 8.40 lakh tons of Blast Furnace grade Coke per year, one of the key raw materials for Hot Metal production.
Speaking after launching the commission activities of new Coke Oven Battery-5 project complex with lightning up of Chimney of Battery, RINL Chairman and Managing Director P K Rath, congratulated all the persons involved in the Battery Project and stressed the importance of the commissioning of the Battery as per schedule.
He exhorted them to put all out efforts to achieve the same with strict adherence to safety standards.
Battery heating will be taken up after achieving required draft in the chimney, which will take about 10 to 15 days. Chimney is 120 M tall RCC structure (2450 cum) with inside refractory work (1300 tones). The Chimney is designed to exhaust the waste flue gas generated during operation of the battery, the steel plant said in a release here.
The Battery with Chimney is being constructed by BEC consortium under the consultancy of M/s MECON Limited.
COB-5 is to cater to the Coke requirement of the plant which was expanded to 6.3 mtpa Liquid Steel capacity.
RINL also added one more million ton by modernizing and revamping the existing production units, thus taking the overall capacity to 7.3 mtpa.
The COB will be similar to the existing ones, 7 metre tall and 67 Ovens each and a By-product recovery – Top charge type battery.
The COB-5 will generate 14 MW of power through waste heat recovery project also.
RINL is presently having four Coke Oven Batteries producing 2.48 million Tons of BF grade Coke. The Coke requirement for the Blast Furnaces (net & dry) for 6.5 mtpa capacity has been estimated at 2.88 mtpa with 15 per cent ash content.
Plant Director (Commercial ) P Raychaudhury, Director (Personnel) KC Das, Director (Finance) VV Venugopal Rao, Executive Director (projects In-charge) R Nagarajan , Foreign experts from Giprokoks and CUI, BEC and other senior officials were also present on the occasion.
