Balance+, Adaptive Control Concept
Combining decades of experience and expertise, ÅF offers Balance+.
Providing modern control solutions for all types of boiler plants, ÅF combines years of experience to create its adaptive control concept called Balance+.
Regardless of the type and size of a boiler plant, Balance+ tackles the challenges that conventional control solutions have difficulty with.
Typically, these challenges come from non-linear multi-variable behaviour, time-delays, furnace slagging, mechanical ageing, and varying fuel quality. Balance+ takes care of all that without time-demanding tuning procedures.
At the heart of Balance+ is an intelligent adaptive process model. Unlike traditional control solutions Balance+ measures direct and indirect data from the process, refers to historical data, and calculates output for controllers.
Balance+ calculates the optimal main control variables for a boiler:
- Feed water to match steam production
- Fuel flow to vaporize feed water
- Air to provide stable combustion and optimal staging
- Spray water to stabilize steam temperatures
- Correct actions to compensate disturbances.
Balance+ has already been applied with the I&C systems of ABB, Siemens, Metso and Honeywell.
