Co-Combustion Investigation of Wood Pellets Blended with FFP2 Masks: Analysis of the Ash Melting Temperature

The COVID-19 pandemic brought a period of high consumption protective masks and an increase in their waste. Therefore, it was necessary to look at possibilities for disposal. This article is focused on the disposal FFP2 form pellets blended with sawdust. Further, ash melting behavior observed. method preparation can impact resulting values temperatures. this investigates temperatures determined during different preparations, such as (550 °C 815 °C) size (non-sifted, smaller than 50 µm 100 µm). All measured deformation were higher 1100 even 1200 some samples. Moreover, presence only insignificantly affected compared pure wood pellets. also showed that increasing temperature from 550 temperature. most significant proportion fraction observed beech 5% 10% spruce °C.
