Performance of Wet and Dry Bagasse Combustion in Assalaya Sugar Factory - Sudan

Abdalla Mohamed Abdalla*, Tagelsir Hasan Hassan and Mohamed Eltayeb Mansour

This Paper aims to study performances of dry and wet bagasse combustion to generate 51.58 kg/s of superheated steam in Assalaya Sugar Factory thermal power plant, wherefore, 26 kg/s of bagasse flows with constant rate (proposed design). Boilers efficiencies and evaporation coefficients has been calculated for each type of bagasse. Indirect heat balance method is used for defining amount of heat lost through boilers, which consists of incomplete combustion, unburnt bagasse, surface radiation, heat transferred by convection, and energy lost by ash. Bagasse combustion analysis for heat value and combustion requirements carried out based on chemical reaction method (stoichiometric quantities). There is a great contrast of boiler efficiency when used dry or wet bagasse (50% moisture), resulted as 52% and 84% respectively. The evaporation coefficient of wet bagasse is inversely proportional to bagasse moisture contains.
