New Delhi: SAIL’s Rourkela Steel Plant (RSP) has won the ‘Greentech Energy Conservation Award 2021 in Platinum’ category presented by Greentech Foundation for outstanding initiatives and practices adopted to conserve energy.
The steel Plant, under the guidance of its CEO Dipak Chattaraj who possess in-depth knowledge about energy management, Rourkela Steel Plant has forayed into various ventures for reducing energy consumption by adopting renewable energy sources and ensuring a pollution-free environment.
The competition was organised in 2 phases, i.e. submission of application followed by a presentation and question-answer round. The presentation session was handled by the team from Energy Management Department led by DGM (EMD) BP Pandey and Business Excellence Department led by GM (BE) Chaitali Das under the overall supervision of GM In-Charge (EMD) KK Pandey.
The jury profusely praised Rourkela Steel Plant for achieving the highest Blast Furnace Gas yield since inception, increased power generation from Power Blowing Station and minimisation of low uncontrolled BF Gas pressure to Coke Ovens Battery – 6.
To achieve these the EMD team had studied the entire system and conducted a pressure survey of BF Gas line to Battery – 6 with respect to BF grid pressure in the modernization zone. Along with the Instrumentation Department, the EMD team redesigned and replaced the orifice with the help of Coke Ovens. Working with the Blast Furnace Department, the EMD team had also increased the BF-5 flare stack PVC set point from 800 mili metre of water column (mmwc) to 900 mmwc.
As a result, the BF gas yield increased to 1685Nm³/ Ton of Hot Metal (THM) in July 2020 which was the all-time best since inception. The power generation from Power and Blowing Station too went upto 25MW, coal consumption was reduced to the tune of approximately 4000 tonne per month in CPP-I, and chimney smoking was prevented. All these had led to substantial savings for the company.
