| Summary: | Optimization of combustion were carried out by managing the amount of air and fuel used. The terms
of optimal means that there is no fuel over used that would increase the production cost and the
amount of toxic waste, and also no energy wasted caused by too much air. Optimization will reduce
the excess air level indicated by percentage of oxygen thus increasing boiler efficiency.
Conventional Air to Fuel Ratio controller cannot guarantee the excess air would be minimum, this is
due to many factor such as limited contact time between air and fuel in the combustion zone.
This final project proposed robust Hoo multivariable control to optimize the combustion process of
boiler. The optimization problem were extended in the Hoo frame work. The Hoo feedback control term
is used to provide robustness to disturbances and modeling uncertainties. The performance were the
then compared to the Air to Fuel Ratio controller.
The Hoo control was succesfully optimized the combustion. This was shown by the average percentage
of oxygen that was reduced from 6.76 % to 2.72% and achieved fuel savings 97 Nm3/hr
