In this paper, for Super304H steel, the growth law of oxide films and heat transfer characteristics between pipe working fluid were investigated by using numerical software ANSYS, which simulated comprehensively effects size, flow rates steam, flue gas temperature, steam temperature on formation thickness film. A bigger wall thickness, a smaller rate or higher will lead faster film flux density through being higher. With increases in film, decreases with small amplitude, average tube walls slightly.
