A raw gas sensible heat recovering method is disclosed. According to the method, a heat exchange device is installed in a riser of a coke oven, and after two thirds of the coking period of the coke oven, a heat exchange medium in the heat exchange device starts to flow so as to recover the raw gas sensible heat. The method is simple in process and prone to implementation. By starting raw gas sensible heat recovery in the specific coking period of the coke oven, the heat recovering is free of scruple, and the problem that waste heat recovery is influenced due to tar coking on heat exchange surfaces can be avoided completely.
