In conclusion, by using small-scale combustor for the applications
where high rate of heat energy is required, smaller size, low
sphericity and low moisture content particle materials such as
sawdust is highly recommended. In case of stable and log lasting
heat energy applications high energy content, moderate particle
size and high sphericity particle materials are suitable. This understanding
can help the engineers, designers and users of biomass
combustion systems to choose the right biomass materials for any
specific heating application.
