The biochars were produced from woody and non-woody biomass by pyrolysis.
Woody biomass showed higher biochar and energy yields than non-woody biomass.
Woody biomass showed lower decomposition rate than non-woody biomass.
The biochars exhibited significantly improved combustion behaviors.
Slagging and fouling issues were similar for raw biomass and biochars combustion.
