Abstract

Low air-concentrations of various flowing steam-air mixtures have been determined by a sampling loop process. The process depends upon the measurements of the vacuum pressure of the remaining air in the sampling loop after immersing it in an ice-water bath. From the insignificant differences of the estimated air-concentrations for the various experimental runs it can be concluded that the sampling loop process is of satisfactory performance in estimating air traces in flowing steam-air mixtures.

Zusammenfassung

Es wurde der Luftgehalt bei niedrigen Luftkonzentrationen verschiedener strömender Dampf-Luft-Gemische mit Hilfe einer Auffangmethode bestimmt. Die Methode beruht auf Messungen des Druckes der Luft, die nach Auskondensation des Dampfes in einem Eis-Wasserbad verbleibt. Aus den geringen Unterschieden zu den berechneten Luftkonzentrationen verschiedener Experimente kann geschlossen werden, daß diese Auffangmethode zufriedenstellend bei strömenden Dampf-Luft-Gemischen niedriger Luftkonzentration arbeitet.
