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.
