If this is a difficult fuel then there must be reasons it doesn't
readily burn the smoke in a secondary flame, have you any especial
reason to think the TlUD secondary combustion is better than any other
secondary combustion chambers? One of the things about TLUD is that it
provides a hot, high calorific value offgas with minimal dilution by
N2 or CO2. Now if, for any reason, this *dry* husk material needs a
much higher primary air then a consequence of this will be the cv of
the offgas will be lower but maybe hotter, Low cv burners need a lot
more mixing and recycling of heat.
