On-line Operating Adjustment of Small Biomass Fired Boilers Optimizing CO and NOx Emissions

Popis výsledku v původním jazyce

Control of combustion conditions in small-scale biomass boilers must be carried out without any high additional costs. If a basic control of heating water is performed by means of a PI control algorithm in a PLC, it can be enhanced with other algorithmstaking care for optimal operating conditions. These conditions are especially efficienty and emissions of unburned hydrocarbons and CO, but also NOx are in interest. The combustion process consists of phenomena that we have little information about for an exact mathematical description. The equations of the chemical reactions are known, but in reality the combustion of biomass is much more complicated and more variable than a mathematical model can express. Therefore, techniques searching extreme are more suitable than controllers requiring a mathematical model in design or tuning. In such a way it is possible to design a controller that is able to control the combustion process effectively over the whole operation range.
