Results are presented for the first phase of an experimental investigation of burnout conditions for flow of boiling water in vertical round ducts. The results are presented in diagrams where for a certain geometry, the burnout steam qualities, x/sub BO/, were plotted against the pressure with the surface heat flux as parameter. The data were correlated by curves. The scatter of the data around the curves was less than plus or minus 5%. In the ranges investigated the observed steam quality at burnout, x/sub BO/, generally decreased with increasing heat flux, increased with increasing pressure, and decreased with increasing mass velocity. The mass velocity effect was exqained on the basis of climbing film flow theory. It was found that for engineering purposes the effects of inlet subcooling and channel length are negligible. (auth)
