El estudio de alternativas que hagan más eficiente la operación de dicha tecnología es de vital importancia.  Objetivo:  Analizar energética y exergéticamente un ciclo de gas que opera con biogás.  Materiales y Métodos:  Se hace uso del simulador ASPEN Plus v10.0 para modelar el ciclo de gas. Se calcularon las eficiencias energéticas y exergéticas del ciclo de gas a distintas condiciones de exceso de aire (EA: 0-170%) y relación de compresión (RC: 10-18).  Resultados y Discusión:  En la condición de operación (EA: 110%, RC: 16) la eficiencia energética y exergética del ciclo fue de 32% y 54% respectivamente. Las mayores pérdidas exergéticas se obtuvieron en la cámara de combustión. La eficiencia exergética de la cámara de combustión aumentó de 69% a 73% al recalentar el aire comprimido con los gases de escape, incrementando a su vez la eficiencia energética y exergética del ciclo a 37% y 55% respectivamente.  Conclusiones:  El incremento del exceso de aire disminuye la eficiencia energética y exergética del ciclo ya que disminuye la temperatura media de aportación de calor. Un aumento de la relación de compresión y/o recalentamiento del aire comprimido disminuyen la destrucción exergética en la cámara de combustión por disminución de la generación de entropía y a su vez se incrementa la eficiencia energética y exergética del ciclo.]]></p></abstract>

The study of alternatives to make this operation technology more efficient has great importance.  Objective:  To analyze energetically and exergetically a gas cycle operating with biogas.  Materials and Methods:  Process simulator Aspen Plus v10.0 was used to model gas cycle. Gas cycle energy and exergetic efficiencies at excess air different conditions (EA: 0-170%) and compression ratio (RC: 10-18) were calculated.  Results and Discussion:  For operating condition (EA: 110%, RC: 16) cycle energy and exergy efficiency were 32% and 54% respectively. Regarding exergy losses, the highest value corresponded to combustion chamber. Combustion chamber exergy efficiency increased from 69% to 73% by reheating compressed air with exhaust gases, increasing besides cycle energy and exergy efficiency to 37% and 55% respectively.  Conclusions:  An increase in excess air decreases cycle energy and exergy efficiencies because average heat input temperature decreases. An increase in compression and/or overheating ratio of compressed air decreases exergetic destruction in combustion chamber by decreasing the entropy generation and increases cycle energy and exergy efficiency.]]></p></abstract>
