摘要

高温空气加热器是高温空气点火试验台的关键设备

将中频加热设备和静态混合器相结合

提出了一种新型的高温空气加热器

并对其运行过程中的电源波动特性、冷热态的阻力特性、加热效率进行了试验研究。与原有的空气加热器进行比较表明

不锈钢材料在中频加热条件下

仍然呈现一定的弱磁性

其冷热态阻力与进口冷空气流速符合幂函数关系。该加热器具有结构简单

加热效率高等优点

明显优于原有的加热器。

Abstract

The high-temperature air heater is a key equipment on the test stand of high temperature air ignition.A new type high-temperature air heater

which is combining medium frequency heating equipment with a static fluid mixer

has been put forward

and test study being carried out to know the fluctuation property of power source

the drag force characters in cold and hot state

and the heating efficiency of the new type air heater.A comparison with the original air heater shows that the stainless steel still has certain weak magnetic property when it is being heated by medium frequency

the relationship of its cold and hot drag force with the inlet cold air velocity conforms to power function.The new air heater has advantages of simple structure and high heating efficiency

being remarkably superior to the original one.
