DORADO, H. O  e  FLOREZ, J. F. Simulation of a process of pulverized coal injection with technical improvements, "Ladrillera La Sultana" case study. Entre Ciencia e Ingenieria [online]. 2015, vol.9, n.17, pp.38-47. ISSN 1909-8367.

Abstract 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 P&ID diagram) using ISA S88 and ISA S5. Eight (8) modules equipment and a furnace module are designed for the process simulator. Two simulations were performed with and without technical improvements incorporated. Temperature curves of furnace were obtained, the standard deviation was +- 5°C lower in the curves with technical improvements incorporated; 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.
