Abstract
A construction and design of coke-oven plant to handle fumes occurring in coke-oven plants, particularly those which are emitted during the pressing of coke from a coke-oven, and which subsequently arise from the coke quenching truck during transportation of the coke to the quenching tower. A deflector apron extends downwardly from the roof towards the quenching truck trackway, to trap fumes in the roof space behind the apron. An extractor duct extends lengthwise of the battery close to the roof, and control means establishes progressive communication between the extractor duct and successive regions of the roof space as the quenching truck passes therebetween.
Claims10
A coke-oven plant comprising:
- i. a battery of coke-ovens;
- ii. a quenching truck;
- iii. a trackway along which the quenching truck travels between the coke-ovens and a quenching tower;
- iv. a roof extending lengthwise of the battery from a position above the doors of the coke-ovens to a position above the trackway;
- v. an extractor duct extending lengthwise of the battery and opening into a roof space beneath the roof;
- vi. control means to establish progressive communication between the extractor duct and successive regions of said roof space as the quenching truck passes therebeneath;
- and
- vii. channelling means to cause fumes emitted from the quenching truck to be directed towards the roof space,
- said channeling means comprising:
- a. a deflector apron extending lengthwise of the battery and downwardly from the roof towards the quenching truck trackway;
- and
- b. a barrier device mounted on the truck, said barrier device comprising a fume deflector member extending lengthwise of the truck and being mounted for movement towards the the coke-ovens from an inoperative to an operative position, and which, when in its operative position, cooperates with the deflector apron to provide, in conjunction therewith, a barrier extending upwardly from the outer side of the quenching truck to the roof.
