无填料喷雾冷却塔在大型火电机组中的应用
|
摘要
对比了大型火电机组中辅机设备冷却水系统采用填料喷雾冷却塔与无填料喷雾冷却塔的技术特点,介绍了无填料喷雾冷却塔的工作原理,并对其节能效益进行了计算。结果表明:与传统型填料喷雾冷却塔相比,采用无填料喷雾冷却塔较大地降低了设备运行维护费用,提高了设备运行的可靠性。
A comparative analysis was conducted on technical features of packing and no-packing spray cooling tower commonly adopted for auxiliary facilities of large thermal power units, while an introduction was made to the working principle of no-packing spray cooling tower, together with a calculation on its energy-saving effectiveness. Results show that, compared with traditional packing spray cooling tower, the application of no-packing spray cooling tower could reduce the operation and maintenance cost, and improve the operation reliability of relevant facilities simultaneously.
