The present invention relates to an apparatus for preventing coke oven gas (COG) from leaking outward by adjusting the pressure in a coking chamber during the charging of coal into the coking chamber. The apparatus for preventing coke oven gas leakage according to an embodiment of the present invention is an apparatus for preventing the coke oven gas (COG) from leaking outward by controlling the pressure in the coking chamber of a coke oven provided with a charging car and a rise pipe, and includes: a pressure detection unit which detects the pressure in the coking chamber in real time; an ammonia injection unit which is connected to a separately provided ammonia tank and injects ammonia from a bent pipe portion of the rise pipe in a direction in which the coke oven gas flows; and a control unit which controls the flow of the ammonia which is injected from the ammonia injection unit during the charging of the coal into the coking chamber by the charging car by comparing a previously input set value to data on the pressure in the coking chamber which is measured by the pressure detection unit. |
