Multimillion pound investments at Tata Steel’s speciality steels business in South Yorkshire have cut energy bills and reduced carbon dioxide emissions by 7,000 tonnes a year, says managing director Mark Broxholme.

One investment alone has reduced energy consumption by 165,000 kWh, reduced CO2 emissions by 82 tonnes a year and paid for itself in less than 12 months.

Savings came after billet mill engineer Patrick Frain identified possible savings from installing an ABB variable speed drive on equipment known as a “scarfer,” which is used at the company’s Stocksbridge plant to remove surface impurities from hi-tech steels.

A propane burner releases the impurities, which are removed by an exhaust fan which used to run at a constant speed, but now runs at 30 per cent until it is needed, when it can be rapidly run up to full speed.

The installation, by Leeds-based Halcyon Drives, also incorporates an energy-saving heat exchanger.
