轮机工程师们一般把蒸发器和锅炉给水换热器看作船舶动力装置独立的组成部分。这种观点正随着喷淋薄膜蒸发器,利用锅炉给水作为蒸发器冷凝管束的冷却介质的成功发展而发生变化。因此,蒸发器便兼有低压给水加热器的作用。把这两个独立的设备装在一起,既能提高整个循环系统的效率,从而降低燃料的消耗率;还可以简化给水系统的管路排列,使结构更为紧凑,经济性更好。 Engineers generally consider evaporators and boiler feed water heat exchangers as separate components of marine power plants. This view is changing with the successful development of showering film evaporators, boiler cooling water, as a cooling medium for evaporator condenser tubes. Therefore, the evaporator will have both the role of low-pressure water heaters. The two independent devices together, both to improve the efficiency of the entire circulatory system, thereby reducing the fuel consumption rate; also can simplify the water supply piping arrangement, the structure is more compact and more economical.
