this paper presents the simulation of a fluidized coal injection process, with and without technical improvements using simulator industrial processes, Ladrillera La Sultana case study, Villa Rica (Cauca). Information of the injection process and furnace tunnel of the plant is collected, classified and organized; the injection process is modeled (physical, process and procedural control and PI the correlation coefficient with the ambient temperature was 0.3 units below with the technical improvement. The implementation of technical improvement means a monthly savings of US $ 171.52.
