Abstract
LA INVENCION SE REFIERE A UN ARBOL (1) DE TURBINA, EN PARTICULAR DE UNA TURBINA DE VAPOR COMBINADO A ALTA/MEDIA PRESION INSTALADA EN UNA CARCASA CONVENCIONAL (22). EL ARBOL (1) DE LA TURBINA PRESENTA EN SU INTERIOR (4) UN CONDUCTO DE REFRIGERACION (5) PARA EL PASO DE VAPOR REFRIGERANTE (6). EL CONDUCTO DE REFRIGERACION (5) ESTA UNIDO EN UN LATERAL A UN CONDUCTO DE DESAGUE (7) Y EN EL OTRO LATERAL A UN CONDUCTO DE ALIMENTACION (8). LA REFRIGERACION MEDIANTE VAPOR DEL ARBOL (1) DE LA TURBINA DE VAPOR COMBINADO A ALTA/MEDIA PRESION SE REALIZA ENVIANDO VAPOR DESDE EL ELEMENTO A ALTA PRESION POR EL CONDUCTO DE ALIMENTACION (8) HASTA EL ELEMENTO A MEDIA PRESION (23) POR EL CONDUCTO DE DESAGUE (7). LA INVENCION SE REFIERE ASIMISMO A UN METODO PARA LA REFRIGERACION DE UN ARBOL (1) DE UNA TURBINA DE VAPOR.
