Closed-loop Combustion Control (ABACO)
Among the results obtained by applying INERCO's combustion optimisation technologies in thermal units, it can be remarked the achievement of heat rate improvements between 0.5% and 1.5%, along with simultaneous reductions in NOX emissions in the range of 15%-40%.
Control of Coal Flow Rate and Particle Size Distribution (ABACO-PCSampler)
Global combustion process optimisation in industrial boilers and furnaces:
o Combustion process balancing.
o Efficiency improvement.
o Carbon-in-ash minimisation.
o Reduction of environmental emissions (NOx, CO2, CO, SOx, particulates, etc.).
o Use of new fuel blends.
o Limitation of operational problems (slagging, fouling, corrosion).
Integration of advanced technologies for closed-loop control of local combustion conditions:
o Combustion monitoring systems.
o New regulation elements.
