Because of the different equipment and external temperature, when the hot water flow, the internal wall of the steam drum will approach the water, the drum temperature will increase. But the temperature of external wall will increase more slowly than the internal one. The higher the temperature difference is, the strong the thermal stress will be. the higher temperature and faster feeding speed of the water will cause larger temperature difference which will result deformation and fissure. Otherwise, it may also cause the uneven inflation of water wall. Therefore, when feeding water to the ship steam fire tube boiler, it is necessary to set a limit to the water temperature and the feeding speed.
