Impingement can be controlled by placing baffle plate tray protections upstream the heat exchanger module; high velocity flow can be handled by oversizing inlet nozzle diameter. […]

[vc_row][vc_column][vc_custom_heading text=\”Molten Salt Corrosion\” use_theme_fonts=\”yes\”][vc_custom_heading text=\”General Considerations\” font_container=\”tag:h3|text_align:left\” use_theme_fonts=\”yes\”][vc_column_text] Molten salts, commonly used as heat transfer fluids in solar power plants, are essentially eutectic mixtures of sodium-potassium nitrates and the nature of these bonds provides strong ionic conditions and good chemical stability of the thermal solution against metal corrosion. However, they are very hygroscopic and

[vc_row][vc_column][vc_custom_heading text=\”Intergranular Corrosion\” use_theme_fonts=\”yes\”][vc_custom_heading text=\”Background\” font_container=\”tag:h3|text_align:left\” use_theme_fonts=\”yes\”][vc_column_text] Austenitic Stainless Steels present corrosion resistance ability due to high chromium (Cr) content. Chromium naturally forms a thin, adherent and very protective passive oxide layer when exposed into corrosive aqueous environment which is primarily the reason of its high resistance capabilities. When austenitic stainless is exposed to a
