摘要
工业现场试验的结果表明,带有小螺旋角的内外螺旋翅片管(简称内外螺旋翅片管或IOSF管)用于电站高压加热器有着显著的传热强化效果,其实测总传热系数是光滑管加热器的1.43倍,可相应节省换热面积30%。在等面积下使用,则可收到明显的节能效果。
The results of an on site industrial test have shown that the use of internal and outer spiral finned tubes (called IOSF tube for short) with a small spiral angle for power station high pressure heaters can bring about a significant heat transfer intensification effect.With a measured total heat transfer factor being 1.43 times of that of a bare tube heater the resulting economy in heat exchanger heating surface can be as high as 30%.It use under an equivalent heat exchange surface area may result in notable energy savings.
