以调查实例强调了保持传热面清洁的重要性 ,通过水垢对对汽轮机冷凝器传热系数影响的计算 ,论证了即使只有 0 .2 5mm的水垢就可以使其下降 3 1.2 %。介绍了自转塑料纽带的自动清洗防垢和传热强化的原理及其试验结果 ,并且进一步计算分析了应用该技术可以为电厂汽轮机带来的增产效益
The investigation example highlights the importance of keeping the heat transfer surfaces clean. Calculations of the effect of scale on the heat transfer coefficient of a turbine condenser demonstrate that even a scale of 0.2 mm can reduce it by 32.2%. This paper introduces the principle of automatic cleaning anti-scaling and heat transfer enhancement of rotating plastic tie and its test results, and further analyzes the application of this technology can increase the efficiency of power plant steam turbine
