An embodiment of the invention discloses an ascension pipe of a coke oven and a method of applying the same to recovery heat of raw coke oven gas. The ascension pipe of the coke oven comprises an inner wall and an outer wall and further comprises a suspension rod fixing rack, a suspension rod and at least one spoiler which is fixedly arranged on the suspension rod; the suspension rod fixing rack is mounted in the ascension pipe of the coke oven; the suspension rod and the suspension rod fixing rack are movably connected, so that the suspension rod is overhung in the ascension pipe of the coke oven and can rotate; at least one outer fluid inlet penetrating through the inner wall and the outer wall is formed on the side wall of the ascension pipe of the coke oven, so that an outer fluid is sprayed to the ascension pipe of the coke oven through the outer fluid inlet and drives the suspension rod and the spoiler to rotate. By adopting the technical scheme provided by the invention, the flow field of raw coke oven gas can be changed, the Reynolds number of coke oven gas flowing is increased and the heat exchange efficiency of the coke oven gas in the ascension pipe is improved, so that the recovery utilization ratio of heat of the coke oven gas is improved and the operating efficiency of the coke oven is improved.
