Range of activities at Gränges in Shanghai
Gränges Shanghai has undertaken a range of activities in 2015 aimed at further decreasing its energy consumption.
Utility Manager Lu Yun explains, “We have, for example, created a new standard operating procedure for our furnace operators, including decreasing open times for the furnace door, introducing a new way to skim, and using solid silicon material instead of silicon powder.”
”We have also upgraded the ventilation system as well as the control system for the workshop to achieve low energy consumption.”
During 2015 Gränges Shanghai managed to lower its electricity consumption to 946 Kw/h per tonne, its use of natural gas to 141 m3 per tonne, and its use of diesel to 2.7 litre per tonne.
“The target for our next step is to decrease electricity consumption to 930 Kw/h per tonne, natural gas to 135 m3 per tonne and diesel use to 2.5 litre per tonne,” says Lu Yun.
