dc.description.abstract | Introducción: Actualmente, el modelado termodinámico de los ciclos de potencia es una herramienta muy atractiva, con la cual se logra analizar y determinar cuan eficiente podría llegar a ser la combinación de distintos ciclos y/o la implementación de diversos componentes, que con sus diversas características y comportamientos impactan de forma positiva sobre la generación de energía. Además de ir ganando importancia en la utilización de tecnologías medio ambientalmente amigables. Objetivo: En este estudio se busca determinar el impacto de los parámetros de funcionamiento de un ciclo Brayton súper crítico respecto a su comportamiento energético y exergético a medida que se realiza la variación de la temperatura del ciclo y demás condiciones de trabajo, tales como uso de calentador y recalentador. Metodología: Se realizó un modelo termodinámico para el análisis energético y exergético de 4 configuraciones de un ciclo Brayton súper crítico con dióxido de carbono como fluido de trabajo, a variados niveles de temperatura y garantizando una presión máxima de 25 MPa. Resultados: Los resultados obtenidos del modelo desarrollado y validado, permitieron verificar que para las configuraciones con recalentamiento se presentan pérdidas totales de exergía consistentemente más bajas que para las configuraciones sin este. Conjuntamente la temperatura de entrada a la turbina y las relaciones de presión tienen una influencia significativa sobre estas pérdidas, obteniéndose su valor mínimo a temperaturas de entre 800-850 °C. Conclusiones: Las pérdidas totales de exergía son menores en las configuraciones que implementan el uso de recalentador que las que no lo usan. Se aprecia que con el uso de recalentador las pérdidas de exergía disminuyen en al menos 3 puntos porcentuales a medida que aumenta la temperatura para todas las configuraciones. | spa |
dc.description.abstract | Introduction− Nowadays, the thermodynamic modeling of the power cycles is conceived as an appropriate device which allows analyzing and determining the adaptability of several cycles as well the implementation and combination of a number of compo-nents whose characteristics and performing work appropriately on the generation of energy, beside of this, the relevant use of environmentally friendly technologies was taking into account as a relevant factor.Objective−This research works intends to determine the impact of the performance parameters from the supercritical Brayton cycle related to its energetic and exergetic performance as the variation of the temperature of the cycle as well alter-native working conditions are executed by using the reheater and heater systems.Methodology−This research project used a thermodynamic model to carry out the energy and exergy analysis from four configurations of the supercritical Brayton cycle along carbon dioxide as a working fluid through several levels of temperatu-re, also a maximum pressure of twenty five MPa was ratified.Results− The obtained results have shown the developed and as-sessed model allowed to demonstrate the configurations through reheat; as for energy there exist a consistently lack of it with regards to the use of the mentioned systems as these have been not configured. In addition the temperature related to the inlet of the turbine and the pressure ratios have a relevant influence on these lacks by obtaining its minimum value at temperatures between 800-850 ° C.Conclusions−It can be said that the total lack of exergy is minor as the configurations from the reheater system as it is applied, in other words it is estimated that through the use of the mentioned system the percentage of reduction aims to three percent as the temperatures increase for the whole configurations. | eng |
