The sugar industry is pursuing diversification options using bagasse as a feedstock. Depithing, the removal of the smaller bagasse particles, is an integral part of theudmanufacturing processes for bagasse by-products such as pulp and paper. There are possible environmental and economic benefits associated with incorporating depithingudoperations into a sugar factory. However there have only been limited investigations into the effects of depithing operations on a sugar factory boiler station. This paperuddescribes a modelling investigation, using the lumped parameter boiler design tool BOILER and the CFD code FURNACE, to predict the effects of pith, depithed bagasseudand mixed bagasse/pith firing on the efficiency, fuel consumption and combustion performance of a typical sugar factory boiler.
