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%.
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.
o Advanced combustion control based on Expert Systems.
Combustion optimisation system based on the accurate monitoring of the combustion process.
Automatic measurement and control of in-furnace local gas concentrations in industrial boilers and furnaces (O2, CO, NOx, CO2, SO2).
Identification of key settings and parameters to optimise emissions and heat transfer through combustion tuning (distribution of fuel and air, excess O2, etc.).
Prevention of detrimental operating conditions in boiler walls.
Technology for the automated sampling of fly-ash and the on-line measurement of carbon-in-ash based on Loss On Ignition (LOI) determination.
Reproduction of reference laboratory techniques used for the measurement of unburned matter in the fly-ash generated in thermal combustion units.
Additional application for the on-line characterisation of parameters such as volatile matter or total moisture in pulverised coal sample.
