Tata Steel makes CO2 savings with blast furnace improvement programme

Steelmaker Tata Steel has said its programme of improvements at its two Port Talbot blast furnaces will reduce the site’s carbon footprint by about 160,000 tonnes of CO2 a year.

The savings are equivalent to the annual emissions from 100,000 cars or those from the energy used by around 50,000 households.

The blast furnaces are powered by high-pressure hot blast air that is superheated to temperatures of more than 1,100°C in seven refractory brick-lined stoves.

An improvement programme of work in three of the seven stoves will upgrade the burners that generate heat, with two new best available technology units being installed. Many of the refractory bricks that store heat and make hot blast air are also being replaced. The work is being carried out while the remaining operational stoves are in use.

Tata Steel Project Manager Andrew McGregor, said: “The stoves are absolutely critical to the running of our blast furnaces. Any loss of efficiency in heating the air means we either have to use more gas than is optimum, or we have to replace that lost energy by using more metallurgical coke to chemically reduce the iron ore inside the furnaces.”
