汽轮机冷凝器自转塑料纽带自动在线除垢防垢技术

Online continuous cleaning foul and anti-foul technology of self-rotating plastic twisted tapes for condensers equipped on steam turbines

通过调查实例强调了保持传热面清洁的重要性 ,在计算水垢对汽轮机冷凝器传热系数影响的基础上 ,论证了仅 0 2 5mm厚的水垢会导致传热系数下降 31 2 % ,介绍了自转塑料纽带的自动除垢防垢和传热强化的原理及其试验结果 。

The importance of keeping the heat transfer surface clean is emphasized by practical studies.Based on calculating the effect of water foul on heat transfer coefficient of condensers of steam turbines,it is proved that the heat transfer coefficient will be reduced by 31 2% even if the thickness of water fouling is only 0 25 mm.The technology and principle of intensification of heat transfer were introduced and the experimental results were also shown.The economic benefits for power plants are also analyzed and figured out.
