Abstract
The bagasse is a by product in Sugar cane factories. Most of Sugar
cane factories use bagasse as a fuel in their boilers for raising steam
which is used is driving their machinery and for processing.
Bagasses from the mills contain about 50 % of its mass as moisture
which must be evaporated before combustion. Part of the energy released
by burning the moist bagasse is lost in evaporating the moisture.
Of the flue gases are used in a dryer, a good portion of the energy lost
is recovered. For this the research is directed for designing,
manufacturing, erecting and testing a dryer to partially dry the bagasse.
The model was erected in the heat engine laboratory of the faculty of
Engineering of the University of Khartoum. It is 60 x 60 x 225 cm.
Exhaust gases of the Perkins Diesel Engine are used. The engine speed
was adjusted to give the temperature of the flue gases as measured in
Assalaya Sugar Cane Factory. The wet bagasse was fed through a hopper
at the top of the dryer and hot gases are fed from the bottom i.e the flow
is counter.
The moisture content of the used bagasse was evaluated before testing
and after a study state was maintained a sample was used for reevaluation
of the moisture content and the dryness calculated.
The achieved dryness is 75.24 %. The saving in bagasse is calculated
and was found equal about 1.387 x 105 tonnes per year. The heat of this
size of bagasse is equivalent the heat in 24966.889 tonnes of furnace and
according to the present prices it is worth 9.4 million Sudanese pounds.
