The experimental research on the sodium spray fire

DU Hai-ou,WANG Rong-dong,HU Wen-jun (China Institute of Atomic Energy,Beijing 102413,China)  
This paper represents the design process on the test of the sodium spray fire,and how to make the liquid sodium into spraying flow,and described the construction of the trial control system and the data collecting system at the same time.During the whole test,by comparing with the temperature and pressure curve obtained by the test and computing by way of FEUMIX process,the conclusion is as follows: In the process of the experiment,the spray sodium burned mainly by way of columned sodium fire.During the sodium spray,the temperature of gas in the spray fire burning zone increased rapidly,and the higher initial peak gas temperature was observed.At the time of 200 s after sodium spray,the temperature of the gas up 1 500 mm aera away from the burning zone approached to the temperature computed by FEUMIX process assuming sodium atomized at 10%,but the curve of pressure is very different.
