Energy-saving type quick-assembled boiler with partition zone accurate heat transmission

The invention provides an energy-saving type quick-assembled boiler with partition zone accurate heat transmission. A method of partition zone accurate heat transmission is used, boiler water is partitioned, saturated or approaching saturated high-temperature water is supplied to high-temperature evaporated heating surface, and the evaporation efficiency of the evaporated heating surface is improved; and low-temperature cold water is supplied to other heating surfaces which have relative low smoke temperature and play a water heating role, so that a low-temperature smoke segment convection heating surface is in a cold water area, a high-temperature smoke segment convection heating surface is in a hot water area, the heat exchange effect is improved by improving a temperature difference ofa smoke side and a water side, and the use ratio of metal materials of the heating surfaces is improved. 种分区精准传热的节能型快组装锅炉，使用分区精准传热的方法，对锅炉炉水进行分区，对于高温的蒸发受热面，供给其饱和或者接近饱和的高温水，提高其蒸发效率；对于其他烟气温度相对较低起到水加热作用的受热面，供给低温冷水，使低温烟气段对流受热面处于冷水
