Raising the Operational Reliability of the Steam Generator of a BN-600 Power Unit in Starting Regimes

摘要

Experimental data are presented on the hydrodynamic instability of the steam-water flow in a once-through sodium-heated steam generator that occurs when the relative outlet enthalpy is more than unity. Effects of the time of operation on the change in the flow stability are revealed. Stability charts for the steam generator's evaporation modules are proposed, and recommendations for preventing the occurrence of instability in starting regimes are given.
