Direktkondensation mit Hilfe von Tauchvorlagen

Investigations on direct contact heat transfer between two fluid phases with simultaneous change of phase in submerged condensers have been extended to the effect of non condensible gases in bubble condensation in an immiscible liquid, in order to enlarge the basis for the design of detention equipments in emergency pressure release systems. In an experimental work the dependency of the condenser efficiency on the main variables (steam throughput, content of inertia, height and temperature of cooling columns, bubble dispersion) has been studied using condenser columns up to 3 m height and 100-300 mm inner diameter. At a cooling liquid column height of #>=# 0.5 m thermodynamic equilibrium between gas and cooling liquid is achieved. Gas contents in condensed systems can be described by the conventional equations, e.g. the equation by Ajita/Yoshida.
