Abstract

EN UN PROCEDIMIENTO PARA REFRIGERAR LA TURBINA PARCIAL DE BAJA PRESION DE UNA TURBINA DE VAPOR (1) CONECTADA EN UN CIRCUITO DE AGUA/VAPOR (12), UN REFRIGERANTE (K'') CIRCULA POR UNAS PIEZAS (24) DE LA TURBINA PARCIAL DE BAJA PRESION (2), EN ESPECIAL EN FUNCIONAMIENTO EN VACIO. PARA UNA REFRIGERACION ESPECIALMENTE EFECTIVA CON UN APROVECHAMIENTO SIMULTANEO DEL CALOR CON ELLO OBTENIDO, SE EMPLEA COMO REFRIGERANTE (K'') UN CONDENSADO (K), EXTRAIDO DEL CONDENSADOR (4) POSCONECTADO A LA TURBINA DE VAPOR (1), QUE ENTREGA AL CIRCUITO DE AGUA/VAPOR EL CALOR RECIBIDO DURANTE LA REFRIGERACION. CON ESTE FIN, LA TURBINA PARCIAL DE BAJA PRESION SE HA CONECTADO A UNA TUBERIA DE REFRIGERANTE (22, 22'') UNIDA AL LADO DE SALIDA DEL CONDENSADOR (4), EN LA QUE SE HA SITUADO UN INTERCAMBIADOR DE CALOR (16, 16'') CONECTADO AL CIRCUITO DE AGUA/VAPOR (12).
