Title (EN) TOP-PRESSURE RECOVERY TURBINE DEPOSITION CONTROL
(FR) CONTRÔLE DU DÉPÔT DANS UNE TURBINE DE RÉCUPÉRATION DE LA PRESSION DU GAZ DE HAUT-FOURNEAU
Abstract:
(EN) Disclosed are methods useful in applications relating to blast furnace processes. The methods of the present invention provide enhanced deposition inhibition of particulate matter in top-pressure recovery turbines. The methods of the present invention comprise adding nitrogen-containing compounds to a top-pressure recovery turbine, inhibiting deposition of solids formed from blast furnace gas on top-pressure recovery turbine components.
(FR) L'invention concerne des procédés utiles dans des applications se rapportant à des procédés de haut-fourneau. Les procédés de la présente invention empêchent de manière améliorée le dépôt de matière particulaire dans des turbines de récupération de la pression du gaz de haut-fourneau. Les procédés de la présente invention comprennent l'ajout de composés contenant de l'azote à une turbine de récupération de la pression du gaz de haut-fourneau, l'inhibition du dépôt de matières solides formées par le gaz de haut-fourneau sur des composants de turbine de récupération de la pression du gaz de haut-fourneau.
