Title (EN) METHOD FOR CONTROLLING THE EMISSIONS FROM A SLOT TYPE COKE OVEN
(FR) PROCEDE D'ELIMINATION DES EMISSIONS D'UN FOUR A COKE DE CONFIGURATION ETROITE
Abstract:
(EN) A method for controlling door and stack emissions from a slot type coke oven. A clean, neutral or nonoxidizing gas under pressure is introduced into a gas chamber (18) in the coke oven door (1) formed between a pair of door seals (11) on the coke oven door. The coke oven gases inside the oven in the vicinity of the coke oven door are allowed to flow freely in a vertical direction to reduce the pressure variability against the inner door seal. The collecting gas main pressure is maintained substantially equal to or less than the pressure at the top of the heating flue of the oven.
(FR) Procédé d'élimination des émissions émanant de la porte et de la cheminée d'un four à coke de configuration étroite. Un gaz propre, neutre ou non oxydant sous pression est introduit dans une chambre à gaz (18) se trouvant dans la porte (1) du four à coke formée entre une paire de joints d'étanchéité (11) de porte située sur la porte dudit four à coke. On laisse s'écouler librement les gaz de four à coke se trouvant à l'intérieur du four à proximité de la porte de ce dernier dans un sens vertical, afin de réduire la variabilité de pression contre le joint d'étanchéité intérieur de la porte. La pression du gaz dans le barillet est maintenue sensiblement égale ou inférieure à la pression régnant dans la partie supérieure du carneau de chauffage dudit four.
