Resumen
En el presente trabajo se realiza un estudio técnico económico del impacto del incremento del
tiro directo de la caña al basculador a partir de la aplicación de métodos estadísticos de
regresión lineal de una y varias variables independientes con el rendimiento industrial y la
generación eléctrica, identificadas estas últimas como variables dependientes y representativas
de los efectos en la fabricación de azúcar y de desempeño energético del proceso fabril.
Además con el uso de los histogramas de frecuencias aplicados a las variables estudiadas se
determinó el comportamiento estadístico de dichas variables. En ambos análisis con el uso del
STATGRAPHICS ver especializado en tratamientos estadísticos.
Con los valores medios de las variables estudiadas se elaboraron los balances de masa y
energía según metodología de Espinosa Pedraja y soportada en una hoja de cálculo del
software Microsoft Excel del paquete Office – 2010, lo que posibilitó la evaluación en
condiciones reales del arreglo del esquema energético actual del Central Azucarero Antonio
Sánchez.
La selección de las bases de datos utilizadas contempla dos contiendas azucareras en ambos
centrales y son las que en el periodo de los últimos 5 años se mostraron más completas y
confiables para la realización del estudio.
Además se realiza un análisis económico del comportamiento de los costos de producción de
azúcar a las condiciones de trabajo actuales en aras de complementar el estudio.
Además se arriba a conclusiones que dan respuesta a los objetivos planteados y se proponen
recomendaciones.
In the present work a technical economic study of impact of increment of direct fire of the cane accomplishes to the tilter starting from the application of statistical methods of linear regression of one and several independent variables with the performance industrial and the electric generation, once these were identified last like dependent variables and representatives of the property in the manufacture of sugar and of energetic performance of manufacturing process. Besides the statistical behavior of said variables determined variables gone into itself with the use of the block diagrams of frequencies applied. In both analyses with the STATGRAPHICS's use seeing specialized in statistical treatments. With the mean values of variables gone into they made the balances out of mass and energy according to methodology of Espinosa Pedraja and borne in the software's spreadsheet Microsoft Excel of the parcel Office - 2010, what the evaluation in real conditions of repair of energetic present-day scheme of the Sugar Mill made possible . The selection of the data bases utilized has provision for two disputes sugar bowls in both central and music them than in the period of the last ones they evidenced 5 years more complete and reliable for the realization of study. Besides an economic analysis of behavior of production costs of sugar comes true to the present-day working conditions for the sake of complementing study. Besides he comes near to conclusions that they give answer to the objectives presented and they intend recommendations.
