Abstract

METODO Y APARATO PARA CONTROLAR LA TEMPERATURA DEL VAPOR DE UNA TURBINA DE VAPOR PARA MINIMIZAR ESFUERZOS TERMICOS. UN SISTEMA DO TURBINA QUE TIENE UNA CAJA DE DISTRIBUCION DE VAPOR ACOPLADA, OPERATIVAMENTE, CON UNA TURBINA DE VAPOR, INCLUYE UN APARATO PARA CALDEO CONTROLADO DE LA CAJA CON UNA FUENTE DE VAPOR A TEMPERATURA CONTROLABLE. UNA VALVULA DE ESTRANGULACION ESTA CONECTADA ENTRE LA FUENTE Y LA CAJA PARA REGULAR EL FLUJO DENTRO DE UN MARGEN DE CAUDALES DE VAPOR. UN SENSOR DE TEMPERATURA ESTA ACOPLADO A LA CAJA, PROPORCIONANDO SEÑALES INDICATIVAS DE LA TEMPERATURA DE LA CAJA. UNA LINEA DE FUGA DE VAPOR, ACOPLADA A LA CAJA, INCLUYE UNA VALVULA DE CONTROL DE FLUJO PARA REGULAR EL FLUJO DESDE LA CAJA POR LA LINEA, Y UN CONTROLADOR ESTA ACOPLADO CON LA VALVULA DE ESTRANGULACION Y LA VALVULA DE CONTROL CONTROLADO LOS FLUJOS ENTRANTE Y SALIENTE DE LA CAJA.
