Abstract

PROCEDE POUR PRODUIRE DE LA VAPEUR DE PROCEDE A UNE PRESSION ET UNE TEMPERATURE UTILES, EN COMPRIMANT UNE ALIMENTATION DE VAPEUR BASSE PRESSION. IL COMPREND LES ETAPES CONSISTANT A AMENER UN MELANGE A DEUX PHASES D'EAU ET DE VAPEUR DANS L'ENTREE D'UN COMPRESSEUR A VIS HELICOIDALE, POSSEDANT UNE PAIRE DE VIS S'ADAPTANT L'UNE A L'AUTRE, ENTRAINEES PAR DES PIGNONS DE TRANSMISSION ET A FAIRE EVAPORER LE CONSTITUANT EAU DU MELANGE A L'INTERIEUR DU COMPRESSEUR POUR PRODUIRE DE LA VAPEUR DE PROCEDE UTILE, SENSIBLEMENT SATUREE. APPLICATION NOTAMMENT DANS LA PRODUCTION DE FER ET D'ACIER, LE RAFFINAGE DU PETROLE, DANS LES INDUSTRIES DU PAPIER, DE L'ALUMINIUM, DU CUIVRE ET DU CIMENT ET DANS LE CHAUFFAGE D'ESPACES.PROCESS FOR GENERATING PROCESS STEAM AT USEFUL PRESSURE AND TEMPERATURE BY COMPRESSING A LOW PRESSURE STEAM SUPPLY. IT INCLUDES THE STEPS CONSISTING OF BRINGING A TWO-PHASE MIXTURE OF WATER AND STEAM INTO THE INLET OF A HELICOIDAL SCREW COMPRESSOR, HAVING A PAIR OF SCREWS ADAPTING TO ONE ANOTHER, DRIVEN BY PINIONS OF TRANSMISSION AND TO EVAPORATE THE WATER CONSTITUENT OF THE MIXTURE INSIDE THE COMPRESSOR TO PRODUCE USEFUL, SENSITIVELY SATURATED PROCESS STEAM. APPLICATION ESPECIALLY IN THE PRODUCTION OF IRON AND STEEL, THE REFINING OF OIL, IN THE PAPER, ALUMINUM, COPPER AND CEMENT INDUSTRIES AND IN THE HEATING OF SPACES.
