EXPERIMENTAL INVESTIGATION OF ASYMMETRIC HEAT TRANSFER MECHANISM IN FURNACE TUBES OF STEAM GENERATORS WITH SUPERCRITICAL PARAMETERS

Outcomes of discovered asymmetric heat transfer mechanism in furnace tubes of actually functioning steam generator with supercritical parameters are given. Investigations were conducted by temperature on-screen insets and heat flow meter in the range of power of 150-330 MWt. Border of active (80%) and passive (20%) zones in cross sections of furnace tubes is set. Determination error is ct± 15% and reproducibility of tests is 0,8-1,5%.
