The present paper describes the results of the retrofitting of a bagasse-fired boiler (RETO CV-25-18) in the sugar mill "Amancio Rodriguez", located in Las Tunas, Cuba. The boiler was modified in order to implement a suspension-burning configuration.
Among other modifications, the distribution of combustion air along the furnace was redesigned in order to obtain a large-scale swirling-flow pattern above the grate. As a result, the new aerodynamic organization of the fuel-air mixture within the furnace was significantly improved.
The combustion efficiency of the boiler before and after the retrofitting is analyzed in this paper. The results of the analysis show that the gross efficiency calculated for the modified boiler increased by 1.91%. This difference is due mainly to the decrease of the heat losses by mechanical unburned matter from about 4% before the retrofitting to 1.95% with the new configuration.
