本发明适用于冶金烧结技术领域，提供了种烧结冷却机余热利用系统，烧结冷却机与余热锅炉通过进出烟气管道连接，烧结冷却机内的烟气经过烟气管道进入余热锅炉，烟气对余热锅炉内部的汽水加热产生饱和蒸汽，烟气冷却降温后重新进入烧结冷却机冷却烧结矿成品热料；余热锅炉的产品蒸汽出口与蒸汽蓄热器的入口连接，饱和蒸汽进入蒸汽蓄热器中，以热能形式进行存储；经过蒸汽蓄热器的饱和蒸汽进入汽轮发电机，进行膨胀做功带动汽轮发电机发电，凝结水重新进入余热锅炉中。利用熔盐储热系统和蒸汽储热器将烟气的热量存储起来，汽轮机不需要跟随烧结冷却机停机，可以在定程度上缓冲烟气温度波动导致蒸汽温度的变化。 The invention belongs to the technical field of metallurgical sintering and provides a waste heat utilization system for a sinter cooler. The sinter cooler and a waste heat boiler are connected through a smoke inlet and outlet pipeline. Smoke in the sinter cooler enters the waste heat boiler through the smoke pipeline. Steam water in the waste heat boiler is heated through the smoke, so that saturated steam is generated. The smoke enters the sinter cooler again to be used for cooling hot finished sintered ore materials after being cooled. A product steam outlet of the waste heat boiler is connected with an inlet of a steam heat accumulator. The saturated steam enters the steam heat accumulator to be stored in the heat energy form.
