Improving bagasse-furnace combustion and modelling* [Full subscriber]

Abstract         The control of bagasse combustion in the furnace is an important part of boiler operations for sugarcane factories.  High bagasse moistures and/or high boiler steam loads can lead to furnace combustion issues.  Significant effort has been carried out, for example, in improving boiler operating procedures and equipment interlocks to minimize the probability of such occurrences.  This paper has considered options and designs to reduce the likelihood of bagasse deposition on furnace grates and resultant furnace instability.  The literature described a modified conventional spreader design that resulted in improved combustion.  The computational fluid dynamics (CFD) software code FURNACE, was used…
