Project: Control Potential of Different Operating Methods in Small-Scale Wood Pellet Combustion

In small-scale solid biomass-fired systems the most severe disturbance is the fluctuation of energy content in the fuel feed. So far, no cost-effective feedforward solution for his disturbance has been presented. The goal of this project was to compare the control potential of different domestic wood pellet burners (< 20 kW) based on direct combustion and on gasification. The comparison was done both in theory and in practice with respect to cost effectiveness, burning efficiency and emissions. When combining the two theoretical models developed in the project, a comprehensive monitoring method for small-scale wood-pellet combustion is achieved, which provides upgraded information on how to control the process to achieve higher efficiency with minimised emissions. However, a lot of work is still necessary in order to make such a concept for estimating efficiency, flue gas and air flow based on physical and data-based models commercially available in combustion units.
