Closed-loop Combustion Control (ABACO)

• Global combustion process optimisation in industrial boilers and furnaces:
  
  • Combustion process balancing
  • Efficiency improvement
  • Carbon-in-ash minimisation
  • Reduction of environmental emissions (NO_x, CO₂, CO, SO_x, particulates, etc.)
  • Use of new fuel blends
  • Limitation of operational problems (slagging, fouling, corrosion)

• Integration of advanced technologies for closed-loop control of local combustion conditions:
  
  • Combustion monitoring systems
  • New regulation elements
  • Advanced combustion control based on Expert Systems

• Main results:
  
  • Improvements in thermal unit heat rate (0.5%-1.5%)
  • Simultaneous NO_x reductions in the range of 15%-40%
  • Control on operational issues (carbon-in-ash, CO production)
  • Efficient use of lower quality or lower priced fuels
