Physico-chemical characteristics of eight different biomass fuels and comparison of combustion and emission results in a small scale multi-fuel boiler

•Physical parameters of the eight biomass fuels examined were all different.•Significant differences were found in Proximate, Ultimate and TGA results.•Energy outputs were not proportionate to dry matter energy content.•Highest flue ash production from fuels with highest fines content.•Flue gas emis...
