Abstract
Gasification as 3 thermochemic31 conversion process of
SOlid \’Jastes and biomass
into gaseous fuels has been
considered in the
present
work. F’artial Combustion
gasification process was studied using an updraft~ air blown,
”ixed bed gasifier. Set of experiments were carried out to
study the effect of 3ir flow rate and fuel particle size on
the performance of the gasifier. The gasifier used in
experiments was made up of a steel cylinder of 20 cm
inner
diameter. and 100 cm long resting on a preforated
steel
plate as a grate.
The inner surface of this cylinder
was
coated by a clay layer of 1.5 cm thickness.
Wood cub es of
different cube sides ( 0.5~ 1.0, 1.5. and 2.0 Cm ) have been
used as the material to be gasified. Experiments were carried
out at four different air flow rates
430. 515,
and
1035 kg/ m2 h ) .
To study the effect of the above two
parameters on the gasifier performance~
the calorific value
of the produced gas and its composition were determined
at
different
operating conditions. The calorific value was
determined using Junikers calorimeter and was noticed
to
increase with the decrease of the particle size The
calorific value was found to increase also with the increase
of the air flow rate to reach a maximum value at a certain
point and
starts deteriorating thereafter,
This point
was
found to be at air flow rate of 735 kg / m2 hr. The calorific
