ABSTRACT

 

Cogeneration has been practiced in the cane industry in Mauritius since 1957. During the crop seasons, cane biomass (called bagasse ) is burned in water-tube boilers of up to 82 bar and fed in condensed extraction steam turbine. Electricity, including supply for national grid, and process heat for cane-milling, distillation and sugar refinery are produced. During intercrop, coal has been used instead of biomass to provide continuous power to the grid. This paper will investigate the current and future potential of cogeneration on the basis of the first law of thermodynamics. Implementation of higher pressure boilers, varieties of biomass of higher calorific value, bagasse drying as well as Bagasse Integrated Gasification Combined-Cycles turbines are also considered as future scenario.
