Abstract

CARACTERIZADO PORQUE DICHO SISTEMA ES UNA PLANTA DE ENERGIA DE TURBINA DE GAS QUE COMPRENDE: A) UN SUMINISTRO DE COMBUSTIBLE LIQUIDO; B) UN DETECTOR, EL CUAL PROVEE UNA SENAL INDICATIVA DE OSCILACIONES EN LA MAGNITUD DE LA PRESION DENTRO DEL COMBUSTOR; C) UN CONTROLADOR QUE INCLUYE: 1) MEDIOS PARA MEDIR DICHA SENAL DE DETECTOR PARA PRODUCIR UNA SENAL MEDIDA INDICATIVA DE LA PRESION DENTRO DEL COMBUSTOR; 2) MEDIOS PARA GENERAR UNA SENAL DE FASE DESFASADA DESDE DICHA SENAL DE DETECTOR; Y 3) MEDIOS PARA GENERAR UNA SENAL DE COMANDO DESDE DICHA SENAL DE FASE DESPLAZASADA; D) UN ACTUADOR DE COMBUSTIBLE, EL CUAL RECIBE COMBUSTIBLE LIQUIDO DESDE DICHO SUMINISTRO. DICHO ACTUADOR PROVEE COMBUSTIBLE LIQUIDO EN UNA TASA MODULADA DE FLUJO EN RESPUESTA A UNA SENAL DE COMANDO; E) UN PREMEZCLADOR, EL CUAL RECIBE DICHO FLUJO DE COMBUSTIBLE DESDE DICHO ACTUADOR Y LA PORCION DE FLUJO QUE NO INGRESA AL PREMEZCLADOR CONSISTE EN UN FLUJO DE COMBUSTIBLE EN UNA TASA CASI UNIFORME. DICHO PREMEZCLADOR MEZCLA EL COMBUSTIBLE LIQUIDO CON AIRE COMPRIMIDO PROCEDENTE DE UN COMPRESOR, DONDE LA PROPORCION COMBUSTIBLE/AIRE ES DE 0,4 A 0,6 Y PROVEE DICHA MEZCLA AL COMBUSTOR; F) UN COMBUSTOR, DONDE SE SOMETE A COMBUSTION DICHA MEZCLA; Y G) UNA TURBINA, QUE RECIBE PRODUCTOS DE LA COMBUSTION
