摘　　要：受机组背压的限制,直接空冷机组运行的经济性和稳定性均会受到一定的影响。为了缓解该问题,某电厂进行储冷冷却及多元耦合冷端提效技术改造,研究不同布置方式下储冷水罐的储冷能力以及对机组背压的作用效果。结果表明,圆柱储冷水箱的储冷能力最好,能够明显降低机组背压。Limited by the back pressure of the unit,the operation economy and stability of the direct air cooling unit will be affected to some extent.In order to alleviate the problem,a power plant has carried out the technical reform of storage cooling and multi-coupling cold end improvement,and studied the storage capacity of cold water storage tank under different arrangement and the effect on the unit back pressure.The results show that the cylindrical cold water storage tank has the best cooling capacity and can significantly reduce the back pressure of the unit.
