Abstract

LA PRESENTE INVENTION CONCERNE UN PROCEDE DE DETERMINATION DE L'ETAT DE LA COMBUSTION DANS UN FOUR ET UN APPAREIL POUR LA MISE EN PRATIQUE DE CE PROCEDE. ON DETECTE DE PETITES PULSATIONS DE PRESSION QUI SE SUPERPOSENT A LA PRESSION INTERNE REGNANT DANS LE FOUR 1, PAR EXEMPLE A L'AIDE D'UN CAPTEUR 8, ET ON DETERMINE L'ETAT DE COMBUSTION SUR LA BASE DU MOTIF DE PULSATIONS AINSI DETECTEES EN UTILISANT PAR EXEMPLE UN ANALYSEUR DE FREQUENCES 18, LE RESULTAT DE CETTE DETERMINATION ETANT UTILISE POUR ASSURER LA COMMANDE DE COMBUSTION EN VUE D'UNE AMELIORATION DU RENDEMENT ET D'UNE REDUCTION DE LA POLLUTION DE L'ENVIRONNEMENT. ELLE SE RAPPORTE A DES FOURS INDUSTRIELS.
