Abstract (en)
[origin: US5609731A] PCT No. PCT/EP93/01817 Sec. 371 Date Mar. 2, 1995 Sec. 102(e) Date Mar. 2, 1995 PCT Filed Jul. 12, 1993 PCT Pub. No. WO94/01513 PCT Pub. Date Jan. 20, 1994A process is disclosed for regulating the gas pressure in the retort of a coke oven. Pivotable cup valves arranged in the elbows of the ascending pipe are actuated as throttling members according to the pressure curve resulting from gas formation from the coal to be cokefied. Throttling of each individual retort is effected by varying water supply, thus regulating the extent of submersion in water, and regulation follows actual pressure conditions in the retort of the coke oven.
