鉴于多汽源高温差大型分汽缸容易出现热疲劳现象,根据传热学和流体力学原理,对现有的分汽缸结构进行改进,让高低温蒸汽在筒体内的空间通过对流的方式完成热交换,避免了热疲劳的出现。该型号设备已经在工程上使用,并且运转正常。通过分析这种分汽缸的工作原理,发现它已经实现分汽和换热两个作用,根据这个启示,进一步设计出对流式换热器,对流式换热器和传统的换热器比较有非常多的优点,应用范围很广,本文给出三种结构供参考。
In view of the multi-steam source large temperature sub-cylinder prone to thermal fatigue phenomenon, according to heat transfer and fluid mechanics, the existing sub-cylinder structure to improve the high and low temperature steam in the cylinder space by convection to complete the heat exchange , To avoid the emergence of thermal fatigue. This type of equipment has been used in engineering and is operating normally. By analyzing the working principle of this sub-cylinder, we find that it has realized two functions of sub-steam and heat exchanger. According to this suggestion, we further design convection heat exchanger, convection heat exchanger and traditional heat exchanger Many advantages, a wide range of applications, this paper gives three structures for reference.
