PURPOSE: A nitrogen gas ejector device with a mixing derivate is provided to smoothly mix sprayed nitrogen gas by temporarily changing the flow of byproduct gas using the mixing derivates. CONSTITUTION: A connection pipe(110) is connected to a transfer pipe by a flange(111). A mixing derivative(120) is installed in the center of the inner space of the connection pipe and has a hollow body with a penetration hole(122). A high pressure spray nozzle(130) sprays nitrogen gas with high pressure to the mixing derivative. A nitrogen gas heater previously heats supplied nitrogen gas.
