The experimental procedure is as follows. Fuel oil A,
which is similar to diesel, is burnt first for furnace heating. When
the temperature of primary and secondary air exceeds about
180 C, primary air is introduced into the mill to start mill heating.
After a certain period, woody biomass is fed into the mill and theground biomass supplied to the burner. Mill exit temperature and
furnace exit gas temperature are monitored and controlled to stabilise
the operating condition. The stabilisation of mill is judged by
mill differential pressure which is the pressure difference between
upper part inside the mill and primary air chamber. It can be used
as an index which reflects the amount of circulating particles. If the
feeding rate of fuel exceeds the mill capacity, particles circulating
within the mill continuously increase, which causes the mill differential
pressure to increase, too. After mill start-up, the burner is set
to co-firing fuel oil A and wood powder. Fuel oil A is cut off when
woody biomass feeding reaches 1200–1500 kg/h and secondary air
temperature exceeds 200 C. The wood powder is sampled and its
particle size distribution analysed by sieve method (based on JIS
Z8815-1994).
