boiler ash melting chemistry biomass

Biomass Ash – an overview | ScienceDirect Topics

The alkali nature of biomass ashes tends to lower the fusion point of ashes leading contamination; it can be from soil, rocks, plastic, metals, chemical treatments, etc. boilers, will ideally fix all potassium in species with relatively high melting
