India’s Union Minister of Steel Mr Ram Chandra Prasad Singh informed the Rajya Sabha that Steel Authority of India Limited & Rashtriya Ispat Nigam Limited have adopted the Best Available Technologies available globally, in the modernization & expansions projects and improved Techno-economic parameters such as reduction in coke rate, increase in Pulverized Coal Injection rate, improvement in BF productivity etc. resulting in reduction of CO2 emission intensity from a level of 3.1 t/tcs from 2005 to 2.55 t/tcs in 2021.”Best Available Technologies adopted by SAIL & RINL are1. Coke Dry Quenching Technology to recover sensible heat from coke from Coke Oven Batteries to produce electricity2. Top Pressure Recovery Turbine in Blast Furnaces to recover waste Pressure energy of BF gas to electricity3. Sinter Cooler Waste Heat Recovery System in Sinter Plant to produce steam or electricity4. Blast Furnace Hot Stoves Waste Gas Recovery System to utilize the waste to preheat the air entering to stoves. Further, the waste gas at reduced temperature is used to pre heat BF gas & Combustion air5. LD Gas recovery system in Steel Melting Shops to recover LD gas from converter blowing for usage as fuel in reheating furnaces6. Evaporating cooling system in reheating furnaces of rolling mills to generate process steam7. Recuperators& Pre-heaters to recover sensible heat of waste gases from Rolling Mills Reheating Furnaces and Calcination plant kilns
