assuming that the fuel has been completely converted and given that the fuel
contained 1 wt% ash (db)? Which assumption(s) did you have to make for this
calculation and is this entirely realistic?

A thermogravimetric analyzer is a characterization device in which a sample
can be heated in a controlled way (heating rate) while simultaneously measur-
ing its weight. A typical result for an agricultural residue fuel is presented in
Figure 2.9. Explain the different phenomena. What do you conclude regarding
this fuel?
PROJECTS
P2.1
Design and test your own calorimeter to determine the heating value of a
biomass component.
P2.2
Mill a selected biomass species and sieve it. Perform ashing in a laboratory
oven at a selected temperature. What are the impacts of oven temperature
and particle size classes on the determined ash contents? Explain your
observations.
P2.3
Propose and perform an ash fusion test that resembles more closely what
happens in a real biomass combustor.
