Converting Waste Agricultural Biomass into a Resource - UNEP

Detailed Process Description
Kakira Sugar Works
The boilers are constructed for bagasse combustion. The bagasse is gravity
fed into the combustion chamber through chutes at the top of the boilers. The
primary and secondary combustion air is entering the combustion chamber
through ports in the furnace walls. The combustion starts where the bagasse
hits the surface pile.
Kinyara Sugar Works
Recently the boilers have been modified, and pinhole grates have been
installed to 22 improve the combustion process. These grates promote
suspension firing of bagasse instead of pile burning which gives a much better
heat release from the fuel (Jobling, 2004).
Generally the turbines are operated 46 weeks of the year. However,
maintenance work is done to the machines every third week when they are
turned off 16 hours each time. The turbines are operated at a load of 750 kW
each. To handle peeks in the system there are diesel generating plants, which
consist of one generator at 800 kW and one at 400 kW.
