The furnace has a daily capacity of approximately 200 tonnes of glass. An improved design will mean greater efficiency and reduced CO2 emissions.
The new equipment now utilises the flame length to burn more gas, thereby reducing NOx emissions by over 20%. Improvements to the regenerators and an increased wall height have increased the combustion volume, which means that more heat can be recycled.
Meanwhile a new burner system with an oxygen trim facility ensures combustion is optimised, further increasing efficiency.
The furnace rebuild is just part of a major £10m investment which Beatson Clark has made in plant and equipment at its Rotherham base this year. A successful repair was made to the amber furnace in December 2011 and Beatson Clark has also installed new vision based inspection equipment at its factory.
