Tata Steel UK, a subsidiary of Indian steelmaker Tata Steel, has announced a blast furnace repair program that will reduce the plant’s carbon footprint by around 160,000 mt of CO2 per year. This is equal to the annual emissions from nearly 100,000 cars or the energy used by about 50,000 households.

Port Talbot’s two furnaces, which produce around 3.6 million mt of molten iron annually, are powered by high-pressure ‘hot blast’ air heated to temperatures of over 1100°C.

“Stoves are essential to the operation of our blast furnaces. The loss in efficiency in heating the air means that we either have to use more gas than optimal, or we have to make up for the lost energy by using more metallurgical coke to chemically reduce the iron ore in the furnace. This program of activities will make a significant difference to our carbon footprint, our energy costs, and the stability and efficiency of our operations,” said Andrew McGregor, project manager for Tata Steel.

An ongoing upgrade program of work on three of the seven hobs will upgrade the heat-producing burners, with two new units using the best available technology being installed.
