Investigates the flames from biomass combustion

What is it about?

Potassium and sodium emissions from biomass combustion are investigated in terms of their speciation in the ash and optical emission spectra.

Why is it important?

Introduces a non-intrusive and in-situ method to preliminary quantify potassium and sodium emissions. Both these elements damage internal surfaces of a furnace. By preliminary quantifying their emissions, strategies to mitigate them can be made. The study also improves the improves the understanding of alkali metal speciation, and their evolution from the flame area to its formation of compounds in ash.
