PLANT FOR RECTIFICATION OF SMOKE OF COKE FURNACE Russian patent published in 2009 - IPC C10B45/00 F23J15/00 

FIELD: mining.

SUBSTANCE: smoke from the coke-oven battery 1 are taken to the rectification circuit 6 by the smoke exhauster equipped with the directing mechanism 9. In the rectification circuit 6 the smoke goes to the utiliser boiler 7. After the utiliser boiler 7 one part of the rectified smoke is taken to the chimney flue 3 through the adjusting valve 10, and the other part of the cleaned smoke is taken to the gas pipe 13 where the smoke controller 14 is installed. From the gas pipe 13 the smoke goes to the horizontal flue 4 in front of the gate valve 5 during smoke traveling. The part of the rectified smoke delivered to the horizontal flue 4 from the gas pipe 13 is taken through the gate valve 5 to the chimney flue 3, and the other part of the rectified smoke is taken to the rectification circuit 6 of the smoke by the opposite flow through the zone where horizontal flue 4 abuts on the coke furnaces 2.

EFFECT: this invention allows to optimise the hydraulic operation mode of the coke furnace, receive high degree of rectification of the smoke from the coke furnace and to achieve high efficiency of work of the utiliser boiler.
