Valmet's advanced boiler control application for optimized combustion has been successfully commissioned at Catalyst Paper's Rumford Mill in Maine, USA. The new combustion management application optimizes the performance of the paper mill's fluidized bed boiler units 6 and 7.
The application has been integrated into the mill's existing automation system. It enables the mill to improve boiler steam output control and optimize limestone use, steam output variability and grid temperature variability.
Additionally, it's now possible to operate both boiler units in fully automatic control for varying compositions of coal and biofuel. The application also provides the tools to improve operational uniformity across shifts.
Valmet's delivery included a complete Valmet DNA FBB Combustion Manager application, engineering, boiler base control logic enhancements, commissioning, tuning and training. Valmet also provided a Valmet DNA Fuel Power Compensator application that compensates for disturbances caused by fuel quality and amount variations by regulating fuel feeding respectively.
