ABB’s automation and electrification systems help create an environmentally friendly, reliable and efficient operation
ABB, the leading power and automation group, has won an order for the electrification and automation system of a new bioboiler and turbine, including fuel management, from Bomhus Energi in Gävle, Sweden.
Bomhus Energi AB, a joint venture of Gävle Energi AB and Korsnäs AB, will supply steam and electricity to the Korsnäs plant in Gävle as well as district heating to the Gävle town district, with the new bioboiler. “The new boiler will replace an older boiler at Korsnäs, and will be both more environmentally friendly and more efficient,” says Mats Törnkvist, technical manager at Korsnäs and Bomhus Energi AB board member.
The ABB supply scope includes low-voltage switchgears for energy-efficient motor control and monitoring of more than 400 motors, 18 energy-efficient and environmentally friendly Resibloc transformers and shunt capacitors to improve power quality. Bomhus has also ordered an ABB Automation System 800xA for controlling and monitoring the boiler.
“The automation system will control and monitor a complex process with high safety requirements. The boiler, the fuel management, a new turbine and the integration of adjacent process sections must be monitored and 100% controlled, a function that now will be significantly simplified with the new automation system,” says Törnkvist.
In addition to advanced control and monitoring functions, the automation system includes new operator stations, integration of switchgear and motor operations and an environmental report system, as well as real-time monitoring of every instrument circuit. System 800xA will be based on virtual servers, saving space and considerably simplifying system testing and future upgrades.
To create a new joint operator environment, older operator stations will be replaced with new 800xA units for adjacent process sections. The project includes all system work, programming, test runs and commissioning.
The new boiler will be fully operational by fall 2012.
