More beans, less gas January 1st 2006 ABB drives are helping achieve 14 per cent greater efficiency at a new energy centre for a Heinz factory.
The energy centre has four boilers and replaces the existing boiler plant, which is at the end of its operational life. Each boiler has two gas-fired burners supplied by Hamworthy Combustion, fitted with fans to push air into the flame.
These eight fans are controlled by eight ABB standard drives, rated 55kW, which vary the speed of the fans to control the amount of air injected depending on whether a high or low flame is required.
This ability to vary he flame to match steam demand is expected to make the energy centre 14 per cent more efficient than the existing steam plant - which will also cut Nitrous Oxide emissions.
